+# Sentence order
+
+In conversation, the sentence order is relatively loose: SVO, OSV, VSO, VOS,
+SOV are all used. Particularly, they're preferred to be used like described
+below:
+
+- SVO: when the subject is the topic of the sentence
+- OSV: when the object is the topic of the sentence; it's also used as
+    equivalent for passive voice, which Hàäsdáïga does not have
+- VSO: when the verb is the topic, or when the question is about the object
+- VOS: when it's a question and it's about the subject
+- SOV: when the object is a pronoun, especially a reflexive pronoun.
+
+Examples:
+
+> he-nom.ea.sg have-ind.prs.cnt many money-acc.mtl.pl  
+> *He has a lot of money.*
+>
+> die-RESULT-acc.wa.sg he-nom.fi.sg not fear-ind.prs.cnt  
+> *Death, he does not fear.*
+>
+> curse-int.pst.prf you-nom.wo.sg neck-wearing-acc.mtl.sg not?  
+> *Did you curse that necklace?*
+>
+> choose-int.fut.prf you-nom.wo.sg path-acc.ea.sg  
+> *Which path will you choose?*
+>
+> pay-int.fut.prf meal-money-acc.mtl.pl who.nom.sg  
+> *Who will pay for the meal?*
+>
+> I-nom.fi.sg you-acc.wa.sg love-ind.prs.cnt  
+> *I love you.*
+
+While casting magic, the sentence order is always SVO.  Here is an example of
+air shield spell, which is a very simple one:
+
+> air-nom.wa.pl flow-rit.prs.cnt.wa and protect-rit.prs.cnt.ea I-acc.wa.sg  
+> *The air shall flow around me and protect me.*

+# Derivational Morphology
+
+## Nominalization
+
+In all following transformations, where a noun has unknown gender mark *-y*,
+it is replaced with an ambiguous, idiomatic gender or the  gender of a closest
+noun that defines it.
+In the former case, such words would be listed in the dictionary.
+
+| category | transformation | examples |
+|----------|----------------|----------|
+| action   | -zy → -sy      | chopzy (think) → chopsu (the act of thinking) |

+| result   | -zy → -mensy   | chopzy (think) → chopmensu (thought), ghószy (draw) → ghósmense (drawing, picture) |
+| diminutive| -sy → -zìssy  | wuüpsi (dog) → wuüpzìssy (puppy), nùchsa (kid) → nùchzìssa (baby), lìmsi (human) → lìmzìssi (dwarf) |

+- [XKCD][xkcd] (webcomic)

+I would like to translate *A Game of Throne* prologue and some chapters in *The
+Lord of the Rings* as well, but since they're not yet in public domain and they
+are not published under a free license (e.g. Creative Commons), I would avoid

-# Hàäsdáïga
-
-## In-world background
-
-Hàäsdáïga is a dead language spoken by ancient people in Gaïdaäna.
-In the day, there was only one language in the continent, shared by people from
-five peoples: *Wood* farmers, *Fire* hunters, *Earth* monks, *Metal* smiths and
-*Water* seafarers.  They embraced the philosophy and that reflected in their
-languages.  They not only used the language to communicate, but also to define
-a method with which they could control these five natural forces.
-
-Later, as these peoples mixed up, their ability to harness these five natural
-forces strengthened for some and weakened for the others.  Most notably, the
-*Metal* and *Water* people lost almost all of this power, and only a minority
-could still use it.  Science and trade thus became their main strength.  On the
-other hand, *Fire* and *Wood* people could control it so well, they no longer
-needed the language to guide their power.  *Earth* monks were the most pure
-with this power, but chose to distance themselves from others' affairs.
-Naturally, the language was divided into five different languages (and two
-pidgins) and the old way of using natural force was forgotten.
-
-Incidentally, *Arrow*, the son of *Blade* and *Pearl*[^1], re-invented the way.
-Born as a child of a Metal mage warrior and a magicless aristocrat in a
-science-oriented society, he learned to use one heritage to support the other.
-He tried to reconstruct the ancient language and defined a way to use it to combine
-his magic ability.  Independently, *Iceberg*[^1] also discovered it by reading
-old text he was lucky to find
-
-We are interested in the linguistic features of this language as well as its magical
-structure. In this book we discuss both of them.
-
-[^1]: These names are temporary, but they carry the meaning of their future names.

-## Nominal
-
-Nominal declension is based on case, gender, and number, in order.  Each
-parameter is indicated by a phoneme, respectively consonant, vowel, and tone,
-effectively forming a syllable.
-
-### Case
-
-There are five cases:
-
-- **nom** nominative: s
-- **acc** accusative: n
-- **abl** ablative: t
-- **dat** dative: d
-- **gen** genitive: c
-
-There is also vocative case, which is unmarked, but this is rarely used.
-
-### Gender
-
-There are five genders, named after five phases in wǔxíng:
-
-- **wo** wood: a
-- **fi** fire: e
-- **ea** earth: i
-- **mt** metal: o
-- **wa** water: u
-- unknown/mixed: y
-
-### Number
-
-There are three numbers:
-
-- **sg** singular: level tone
-- **sv** several: falling tone
-- **pl** plural: rising tone

-## Verbal
-
-Verbal conjugation are decided by mood, tense, and aspect.
-Infinitive verbs all have the ending -zy, which is changed by conjugation.
-They are respectively indicated by a vowel, a tone, and a consonant.
-
-### Mood
-
-There are five moods:
-
-- **ind** indicative: a
-- **rit** ritual: e
-- **int** interrogative: i
-- **imp** imperative: o
-- **sub** subjunctive: u
-
-### Tense
-
-- **pst** past: falling
-- **prs** present: level
-- **fut** future: rising
-
-### Aspect
-
-- **hab** habitual: j
-- **cnt** continuous: r
-- **prf** perfective: unmarked
-
-### Gender
-
-In the ritual mood, another vowel representing verb's gender is added after the
-aspect consonant.  The vowel is the same as for nominal gender.
-Note that it is not uncommon to use ritual mood without gender, such as when
-insulting.
-
-The dictionary form shows this gender even though it is not in ritual mood.

 # Phonology
-
-<!-- toc -->
-
-## Consonants
-
-Main consonants are listed in the table below:
-
-|               | labial | alveolar | palatal | uvular    | glottal |
-|---------------|--------|----------|---------|-----------|---------|
-| **nasal**     | m      | n        | ɲ (*nj*)  | ŋ (*n*, *ng*) |         |
-| **plosive**   | p b    | t d      |         | k (*c*) ɡ (*g*)   | ʔ       |
-| **fricative** | f v    | s z      |         | x (*ch*) ɣ (*gh*) | h   |
-| **sonorant**  | w      | r l      | j       |           |         |
-
-Notes:
-
-- *n* is pronounced as /ŋ/ only if it is followed by another consonant
-- The glottal stop /ʔ/ is not written. It's implied when a syllable does not
-  have other consonants (similar to Vietnamese).
-- *nj* is pronounced as /ɲ/ even when the two letters are from different words.
-  The sames go for other digraphs (ng, ch, gh).  There is therefore no
-  ambiguous way of pronouncing a word given a romanization.
-- Some dialects may pronounce *s*, *z* as 
-
-## Vowels
-
-|       | front | centre | back |
-|-------|-------|--------|------|
-| open  | i     |        | u    |
-| mid   | e     | ə (*y*)| o    |
-| close | a     |        |      |
-
-Note: the schwa sound /ə/ is not written in the native script.  However, for
-ease of writing on computer, it is romanized as y.  Both kýn and ḱn are
-acceptable as the romanization for the same syllable.  This document is in
-favor of using explicit form instead of implicit form.
-
-### Diphthongs and long vowels
-
-Long vowels are written as duplicated vowels, with the second character having
-a diaresis (for example *aä* is pronounced /aː/). For vowels whose
-romanizations contain two characters, the later vowel is duplicated (for
-example, long version of *aë* is *aëë*)
-
-Diphthongs are written similarly. They're listed below:
-
-- aï /aɪ/
-- aü /aʊ/
-- eï /eɪ/
-- oï /oɪ/
-- uï /uɪ/
-
-## Tones
-
-There are three tones in Hàäsdáïga:
-
-- level tone (a) /˧˧/
-- rising tone (á) /˧˥/
-- falling tone (à) /˥˩/
-
-## Phonotactics
-
-Syllables in Hàäsdáïga have a simple structure: **CVT(C)**
-
-The final consonants can't be sonorants, /h/, /ʔ/, and voiced vowels if they
-have voiceless equivalents.  Other than that, there isn't any constraints.
-
-There are thus:
-
-\\( 22  × (6 × 2 + 6 )  × 3  × 11  = 18876  \\) (possible syllables)
-
-Note: These numbers mean:
-
-- 22 consonants
-- 6 vowels and their long version
-- 6 diphthongs
-- 3 tones
-- 10 final consonants

 # Noun
-
-## Cases
-
-### Nominative
-
-The nominative is used for the subject of a sentence and for vocative.
-
-It is also used as predicative for some verbs:
-
-- wítzy (be)
-- voïczy (become)
-
-TODO: add examples
-
-### Accusative
-
-Accusative case is used for direct object.
-
-TODO: add examples
-
-### Ablative
-
-Ablative case is used to express the motion away from something
-
-TODO: add examples
-
-### Dative
-
-Dative case is used to express the motion to a location, or being at the
-location (locative).  The meaning is determined by whether the verb takes
-object or not.
-
-TODO: add examples
-
-### Genitive
-
-Genitive case is used to express possession or relation.
-
-> **cibansy wítar súngsa fènci**  
-> this-nom.sg be.ind.prs.cnt book-nom.wo.sg I-gen.ea.sg  
-> *This is my book.*
-> 
-> **cisúngsa wítar fènci**  
-> this-book-nom.wo.sg be.ind.prs.cnt I-gen.ea.sg  
-> *This book is mine.*
-
-*Relations* also include relations constructed by postposition.
-
-> **tènze vamá fèncu chát**  
-> he-nom.fi.sg stay-ind.fut.prf I-gen.wa.sg with  
-> *He will stay with me.*
->
-> **vifar bissy wócci mèng**  
-> stand-ind.prs.cnt man-nom.sg shop-gen.ea.sg (in front of)  
-> *There is a man standing in front of the shop.*
-
-Genitive is also used for family name, which is placed before the given name.
-
-## Gender
-
-### Individuals
-
-Nouns' gender are arbitrarily assigned, based on the philosophy.
-Generally, it is quite intuitive, for example, (tree), (seed), (wood) are wood.
-However, there are some cases it is unclear, like (liver) being wood, and even
-counter-intuitive, like (flower) being fire.
-This is because liver is is controlled by wood in the philosophy,
-and flower represents the outburst state which matches more with fire.
-
-For people, gender is determined by their date of birth (people born in wood
-months are wood).  For people who can use magic, their magic affinity is their
-gender.
-
-### Mixed groups
-
-The gender of a group of objects with different genders is determined by the *majority*
-group.  The majority group is defined as the group with:
-
-- more than half of the group
-- has more than 10 members, if any other group has more than one member.
-
-## Number
-
-- singular: zero or one
-- several: two to ten, inclusive
-- plural: more than ten

 # Pronoun
-
-Pronouns are nominal anaphora, that is, short words that are used to refer to a
-noun or a noun phrase.  Pronouns usually have nominal morphology, though not
-strictly.  Pronoun is a closed class.
-
-## Personal pronouns
-
-There are 15 personal pronouns in total.  Dual pronouns and 1st person
-inclusive pronouns are in fact formed by compounding others.
-
-| person | singular | dual     | several | plural   |
-|--------|----------|----------|---------|----------|
-| 1st    | fènsy    | fènvynsỳ | jaächsỳ | rèëchsý  |
-| 1st (inclusive) | | fèndynsỳ | jaächdynsỳ | rèëchdynsý |
-| 2nd    | tènsy    | tèndynsỳ | néëcsỳ  | ngeënsý  |
-| 3rd    | lúcsy    | lúccynsỳ | bóönsỳ  | waanjsý  |
-
-### Reflexive
-
-Reflexive pronouns occur as clitic.  They are formed by removing the gender
-vowel and number tone from corresponding personal pronoun.
-
-> **fènsu fèngòngàr zápmỳfo**  
-> I-nom.wo.sg I-acc-look-ind.pst.cnt mirror-dat.mt.sg  
-> *I was looking at myself in the mirror.*
-
-It also works for indirect object:
-
-> **tènsa tènfnìchá púürijinsechne**  
-> he-nom.wo.sg he-dat-buy-ind.fut.prf birthday-gift-acc.fi.sg  
-> *He'll just buy himself a birthday gift.*
-
-There is a difference between reflexive and reciprocal for plural pronouns.
-
-> **lúccynsỳ lúcnmeërá'ar**  
-> you-nom.dual you-acc.sg-love-ind.prs.cnt  
-> *You love yourselves*
->
-> **lúccynsỳ lúccyǹmeërá'ar**  
-> you-nom.dual you-acc.dual-love-ind.prs.cnt  
-> *You love each other.*
-
-Note: there is also a idiomatic use of reflexive pronouns:
-
-> **fènsu fèncwítar**
-> I-nom.wa.sg I-gen-be.ind.prs.cnt  
-> *I am alone.*
->
-> **fènsu fèncbochar ringyno**  
-> I-nom.wa.sg I-gen-repair.ind.pst.prf vehicle-acc.mt.sg  
-> *I fixed the car myself.*
-
-## Indefinite pronouns
-
-These are indefinite pronouns in Hàäsdáïga:
-
-- hipsy: somewhen
-- vàtsy: somewhere
-- cotsy: somehow
-- bansy: someone
-- wón: which
-
-Construction of other [pro-forms][pro-forms] are totally regular:
-
-- It is interrogative when its verb is in interrogative mood.
-- Its proximity is determined by a determiner prefix: *ci* (this) *la* (that)
-- So are *any*, *all/every*, *other*, with *zòt*, *rýnj*, *púch*, respectively.
-- Negative forms are formed by negating the "all/every" form. See [Negation].
-- The equivalent relative pronouns is unchanged.
-
-[pro-forms]: https://en.wikipedia.org/wiki/Pro-form
-
-Examples:
-
-TODO: add glosses
-
-> **vungà las hipfy**  
-> happen-ind.pst.prf that-nom somewhen-dat  
-> *It happened at some point*.
->
-> **saändasi Aäratraäce voö'ir vàtfy**  
-> city-nom.ea.sg ember-gen.fi be_located_at-int.prs.cnt somewhere-dat  
-> *Where is Ember city?*
->
-> **wónjannane lúcfi càhánì**  
-> which-name-acc.fi.sg you-dat.ea.sg give-int.pst.prf  
-> *What is your name?*
->
-> **vifi bansy civàtfy**  
-> stand-int.prs.cnt someone-nom.sg this-somewhere-dat  
-> *Is there anyone here?*
->
-> **rýnjbansý càï'ar njizy lan**  
-> every-someone-nom.pl can-ind.prs.cnt do that-acc
-> *Everyone can do that.*
->
-> **dy njéna bansa lúcna daïnè'à, connar fènsu**  
-> `<sub>` woman-acc.wo.sg who.nom you-acc.wo.sg help-ind.pst.prf,
-> know-ind.prs.cnt I-nom.wa.sg  
-> *I know the woman who helped you.*

 # Verb
-
-## Tense
-
-There are 3 tenses: past, present, and future.  They are used according to
-time.
-
-### Reported speech
-
-Unlike in English and some other languages, tense is not propagated in reported speech.
-Instead, the tense is relative to the time spoken.
-For example, if John said to Mary "I will meet you at noon" and now
-is after that, you would say:
-
->
-> John-nom.sg Mary-dat.sg say-ind.pst.prf `<sub>` he-nom.sg her-acc.sg meet-ind.pst.prf
-> noon-dat.fi.sg  
-> *John told Mary he would meet her at noon.*
-
-If the future is indefinite, it will stays in the future, whether the event has
-happened or not.
-
-> 
-> he-nom.fi.sg believe-ind.pst.cont `<sub>` she-nom.ea.sg back-come-ind.fut.prf,
-> that-acc.sg she-nom.ea.sg do.ind.pst.prf  
-> *He believed she would come back, and she did.*
-
-### Narration
-
-Narration is always present tense, even when the story obviously happened in the past.
-
-## Mood
-
-- indicative: the action actually occurs
-- interrogative: the action is in the question
-- imperative: the action is a command
-- subjunctive: the action does not happens, and usually used in conditional or wish
-- ritual: the action is the intend of the spellcaster
-
-Ritual mood is also used for cursing and profanity.  In such case, the gender
-affix is removed so the speaker does not accidentally cast the actual curse.
-Because cursing is quite literal for Hàäsdáïga speakers, it is never used in
-the same manner as in the modern society.
-
-## Aspect
-
-- habitual: the action happens repeatedly in the period of time
-- continuous: the action or the state persists over the duration
-- perfective: the action happens once and finished

 # Writing system
-
-The native writing system has not been created yet.
-
-## Glyph structure
-
-Each syllable is represented by a glyph with a structure as shown here:
-
-![The structure of a glyph for a syllable](./glyph.png)
-
-When a component in the syllable is missing, the other components expand to
-fill up the gap.  Long vowel is represented as a horizontal line in the V2
-position.
-
-Because it requires more than a font to be able to write these glyphs, I cannot
-create a font to represent it.  There will be a tool to generate svg/png for
-generaating glyphs from a word, however.  All text samples in this book will be
-romanized, from which you can generate the native scripts.
-
-## Order
-
-Hàäsdáïga does not have an alphabetic order.
-The alphabet order is used for us to more conveniently list words.
-The order for letters with tones is level, falling, and rising.
-
-## Letters
-
-Letters used to form glyphs are listed in the table below:

-| ( or “| ![Hàësdáïga left bracket](fonts/parenleft.svg) |
-| ) or ”| ![Hàësdáïga right bracket](fonts/parenright.svg) |
-
-Punctuation usage:
-
-- Sentence punctuation `. ! ? :` are put at the beginning of the sentence,
-    rather than the end.
-- Colon is considered a sentence punctuation.  It is put at the beginning of
-    the quoted phrase.
-- Comma is used in a similar way as in English.
-- Brackets are used for both quotation and explanation. In case of quotation,
-    there should be a colon preceding the phrase.
-
-# Input for glyph generation
-
-While this is not a part of the language, in order to generate native script
-with the provided tool, one MUST follow this guideline for writing
-romanization, which is not the same as the normal romanization guideline.
-
-- If there is a tone, the schwa `y` must be explicit.  That is, never put the
-    tone on a consonant.
-- The second vowel should not come with the diaresis.
-- Long vowel should be represented by a tilde `~` rather than duplicating
-    vowels.
-- Always write syllables separately.  For example `càhánzy` (to give) must
-    be written as `cà hán zy`.
-- The glottal stop must be explicit.  For example `aäratse` (ash) must be
-    written as `'a~ rat se`.
-- Punctuations should be separated from syllables.
-- Spaces should be noted with a hyphen.
-
-The output may look bad; you can blame my poor drawing skills (I did not align
-some of the strokes) and the limitation of technology (the letters are
-stretched and therefore the thickness is not consistent).

-# Conlangs
+# Hàäsdáïga
 
-I am a hobbyist conlanger and this is my collection of conlangs. Unfortunately,
-I have not digitize my previous work in a standard way.  Either I write it on
-phone note or write Word(tm) document (ew) and upload it to Google Drive (ew).
-Git is more resilient, and now that I have a convenient way of syncing between
-my devices without cloud, hopefully it will be the final version.
+## In-world background
 
-Currently, I am working on Hàäsdáïga, a synthetic language influenced by
-[wǔxíng][wuxing] philosophy. I am also considering building a genderless,
-isolated language after this one.
+Hàäsdáïga is a dead language spoken by ancient people in Gaïdaäna.
+In the day, there was only one language in the continent, shared by people from
+five peoples: *Wood* farmers, *Fire* hunters, *Earth* monks, *Metal* smiths and
+*Water* seafarers.  They embraced the philosophy and that reflected in their
+languages.  They not only used the language to communicate, but also to define
+a method with which they could control these five natural forces.
 
-[wuxing]: https://en.wikipedia.org/wiki/Wuxing_(Chinese_philosophy)
+Later, as these peoples mixed up, their ability to harness these five natural
+forces strengthened for some and weakened for the others.  Most notably, the
+*Metal* and *Water* people lost almost all of this power, and only a minority
+could still use it.  Science and trade thus became their main strength.  On the
+other hand, *Fire* and *Wood* people could control it so well, they no longer
+needed the language to guide their power.  *Earth* monks were the most pure
+with this power, but chose to distance themselves from others' affairs.
+Naturally, the language was divided into five different languages (and two
+pidgins) and the old way of using natural force was forgotten.
+
+Incidentally, *Arrow*, the son of *Blade* and *Pearl*[^1], re-invented the way.
+Born as a child of a Metal mage warrior and a magicless aristocrat in a
+science-oriented society, he learned to use one heritage to support the other.
+He tried to reconstruct the ancient language and defined a way to use it to combine
+his magic ability.  Independently, *Iceberg*[^1] also discovered it by reading
+old text he was lucky to find
+
+We are interested in the linguistic features of this language as well as its magical
+structure. In this book we discuss both of them.
+
+[^1]: These names are temporary, but they carry the meaning of their future names.

+## Nominal
+
+Nominal declension is based on case, gender, and number, in order.  Each
+parameter is indicated by a phoneme, respectively consonant, vowel, and tone,
+effectively forming a syllable.
+
+### Case
+
+There are five cases:
+
+- **nom** nominative: s
+- **acc** accusative: n
+- **abl** ablative: t
+- **dat** dative: d
+- **gen** genitive: c
+
+There is also vocative case, which is unmarked, but this is rarely used.
+
+### Gender
+
+There are five genders, named after five phases in wǔxíng:
+
+- **wo** wood: a
+- **fi** fire: e
+- **ea** earth: i
+- **mt** metal: o
+- **wa** water: u
+- unknown/mixed: y
+
+### Number
+
+There are three numbers:
+
+- **sg** singular: level tone
+- **sv** several: falling tone
+- **pl** plural: rising tone

+## Verbal
+
+Verbal conjugation are decided by mood, tense, and aspect.
+Infinitive verbs all have the ending -zy, which is changed by conjugation.
+They are respectively indicated by a vowel, a tone, and a consonant.
+
+### Mood
+
+There are five moods:
+
+- **ind** indicative: a
+- **rit** ritual: e
+- **int** interrogative: i
+- **imp** imperative: o
+- **sub** subjunctive: u
+
+### Tense
+
+- **pst** past: falling
+- **prs** present: level
+- **fut** future: rising
+
+### Aspect
+
+- **hab** habitual: j
+- **cnt** continuous: r
+- **prf** perfective: unmarked
+
+### Gender
+
+In the ritual mood, another vowel representing verb's gender is added after the
+aspect consonant.  The vowel is the same as for nominal gender.
+Note that it is not uncommon to use ritual mood without gender, such as when
+insulting.
+
+The dictionary form shows this gender even though it is not in ritual mood.

+# Phonology
+
+<!-- toc -->
+
+## Consonants
+
+Main consonants are listed in the table below:
+
+|               | labial | alveolar | palatal | uvular    | glottal |
+|---------------|--------|----------|---------|-----------|---------|
+| **nasal**     | m      | n        | ɲ (*nj*)  | ŋ (*n*, *ng*) |         |
+| **plosive**   | p b    | t d      |         | k (*c*) ɡ (*g*)   | ʔ       |
+| **fricative** | f v    | s z      |         | x (*ch*) ɣ (*gh*) | h   |
+| **sonorant**  | w      | r l      | j       |           |         |
+
+Notes:
+
+- *n* is pronounced as /ŋ/ only if it is followed by another consonant
+- The glottal stop /ʔ/ is not written. It's implied when a syllable does not
+  have other consonants (similar to Vietnamese).
+- *nj* is pronounced as /ɲ/ even when the two letters are from different words.
+  The sames go for other digraphs (ng, ch, gh).  There is therefore no
+  ambiguous way of pronouncing a word given a romanization.
+- Some dialects may pronounce *s*, *z* as 
+
+## Vowels
+
+|       | front | centre | back |
+|-------|-------|--------|------|
+| open  | i     |        | u    |
+| mid   | e     | ə (*y*)| o    |
+| close | a     |        |      |
+
+Note: the schwa sound /ə/ is not written in the native script.  However, for
+ease of writing on computer, it is romanized as y.  Both kýn and ḱn are
+acceptable as the romanization for the same syllable.  This document is in
+favor of using explicit form instead of implicit form.
+
+### Diphthongs and long vowels
+
+Long vowels are written as duplicated vowels, with the second character having
+a diaresis (for example *aä* is pronounced /aː/). For vowels whose
+romanizations contain two characters, the later vowel is duplicated (for
+example, long version of *aë* is *aëë*)
+
+Diphthongs are written similarly. They're listed below:
+
+- aï /aɪ/
+- aü /aʊ/
+- eï /eɪ/
+- oï /oɪ/
+- uï /uɪ/
+
+## Tones
+
+There are three tones in Hàäsdáïga:
+
+- level tone (a) /˧˧/
+- rising tone (á) /˧˥/
+- falling tone (à) /˥˩/
+
+## Phonotactics
+
+Syllables in Hàäsdáïga have a simple structure: **CVT(C)**
+
+The final consonants can't be sonorants, /h/, /ʔ/, and voiced vowels if they
+have voiceless equivalents.  Other than that, there isn't any constraints.
+
+There are thus:
+
+\\( 22  × (6 × 2 + 6 )  × 3  × 11  = 18876  \\) (possible syllables)
+
+Note: These numbers mean:
+
+- 22 consonants
+- 6 vowels and their long version
+- 6 diphthongs
+- 3 tones
+- 10 final consonants

+# Noun
+
+## Cases
+
+### Nominative
+
+The nominative is used for the subject of a sentence and for vocative.
+
+It is also used as predicative for some verbs:
+
+- wítzy (be)
+- voïczy (become)
+
+TODO: add examples
+
+### Accusative
+
+Accusative case is used for direct object.
+
+TODO: add examples
+
+### Ablative
+
+Ablative case is used to express the motion away from something
+
+TODO: add examples
+
+### Dative
+
+Dative case is used to express the motion to a location, or being at the
+location (locative).  The meaning is determined by whether the verb takes
+object or not.
+
+TODO: add examples
+
+### Genitive
+
+Genitive case is used to express possession or relation.
+
+> **cibansy wítar súngsa fènci**  
+> this-nom.sg be.ind.prs.cnt book-nom.wo.sg I-gen.ea.sg  
+> *This is my book.*
+> 
+> **cisúngsa wítar fènci**  
+> this-book-nom.wo.sg be.ind.prs.cnt I-gen.ea.sg  
+> *This book is mine.*
+
+*Relations* also include relations constructed by postposition.
+
+> **tènze vamá fèncu chát**  
+> he-nom.fi.sg stay-ind.fut.prf I-gen.wa.sg with  
+> *He will stay with me.*
+>
+> **vifar bissy wócci mèng**  
+> stand-ind.prs.cnt man-nom.sg shop-gen.ea.sg (in front of)  
+> *There is a man standing in front of the shop.*
+
+Genitive is also used for family name, which is placed before the given name.
+
+## Gender
+
+### Individuals
+
+Nouns' gender are arbitrarily assigned, based on the philosophy.
+Generally, it is quite intuitive, for example, (tree), (seed), (wood) are wood.
+However, there are some cases it is unclear, like (liver) being wood, and even
+counter-intuitive, like (flower) being fire.
+This is because liver is is controlled by wood in the philosophy,
+and flower represents the outburst state which matches more with fire.
+
+For people, gender is determined by their date of birth (people born in wood
+months are wood).  For people who can use magic, their magic affinity is their
+gender.
+
+### Mixed groups
+
+The gender of a group of objects with different genders is determined by the *majority*
+group.  The majority group is defined as the group with:
+
+- more than half of the group
+- has more than 10 members, if any other group has more than one member.
+
+## Number
+
+- singular: zero or one
+- several: two to ten, inclusive
+- plural: more than ten

+# Pronoun
+
+Pronouns are nominal anaphora, that is, short words that are used to refer to a
+noun or a noun phrase.  Pronouns usually have nominal morphology, though not
+strictly.  Pronoun is a closed class.
+
+## Personal pronouns
+
+There are 15 personal pronouns in total.  Dual pronouns and 1st person
+inclusive pronouns are in fact formed by compounding others.
+
+| person | singular | dual     | several | plural   |
+|--------|----------|----------|---------|----------|
+| 1st    | fènsy    | fènvynsỳ | jaächsỳ | rèëchsý  |
+| 1st (inclusive) | | fèndynsỳ | jaächdynsỳ | rèëchdynsý |
+| 2nd    | tènsy    | tèndynsỳ | néëcsỳ  | ngeënsý  |
+| 3rd    | lúcsy    | lúccynsỳ | bóönsỳ  | waanjsý  |
+
+### Reflexive
+
+Reflexive pronouns occur as clitic.  They are formed by removing the gender
+vowel and number tone from corresponding personal pronoun.
+
+> **fènsu fèngòngàr zápmỳfo**  
+> I-nom.wo.sg I-acc-look-ind.pst.cnt mirror-dat.mt.sg  
+> *I was looking at myself in the mirror.*
+
+It also works for indirect object:
+
+> **tènsa tènfnìchá púürijinsechne**  
+> he-nom.wo.sg he-dat-buy-ind.fut.prf birthday-gift-acc.fi.sg  
+> *He'll just buy himself a birthday gift.*
+
+There is a difference between reflexive and reciprocal for plural pronouns.
+
+> **lúccynsỳ lúcnmeërá'ar**  
+> you-nom.dual you-acc.sg-love-ind.prs.cnt  
+> *You love yourselves*
+>
+> **lúccynsỳ lúccyǹmeërá'ar**  
+> you-nom.dual you-acc.dual-love-ind.prs.cnt  
+> *You love each other.*
+
+Note: there is also a idiomatic use of reflexive pronouns:
+
+> **fènsu fèncwítar**
+> I-nom.wa.sg I-gen-be.ind.prs.cnt  
+> *I am alone.*
+>
+> **fènsu fèncbochar ringyno**  
+> I-nom.wa.sg I-gen-repair.ind.pst.prf vehicle-acc.mt.sg  
+> *I fixed the car myself.*
+
+## Indefinite pronouns
+
+These are indefinite pronouns in Hàäsdáïga:
+
+- hipsy: somewhen
+- vàtsy: somewhere
+- cotsy: somehow
+- bansy: someone
+- wón: which
+
+Construction of other [pro-forms][pro-forms] are totally regular:
+
+- It is interrogative when its verb is in interrogative mood.
+- Its proximity is determined by a determiner prefix: *ci* (this) *la* (that)
+- So are *any*, *all/every*, *other*, with *zòt*, *rýnj*, *púch*, respectively.
+- Negative forms are formed by negating the "all/every" form. See [Negation].
+- The equivalent relative pronouns is unchanged.
+
+[pro-forms]: https://en.wikipedia.org/wiki/Pro-form
+
+Examples:
+
+TODO: add glosses

+# Verb
+
+## Tense
+
+There are 3 tenses: past, present, and future.  They are used according to
+time.
+
+### Reported speech
+
+Unlike in English and some other languages, tense is not propagated in reported speech.
+Instead, the tense is relative to the time spoken.
+For example, if John said to Mary "I will meet you at noon" and now
+is after that, you would say:
+
+>
+> John-nom.sg Mary-dat.sg say-ind.pst.prf `<sub>` he-nom.sg her-acc.sg meet-ind.pst.prf
+> noon-dat.fi.sg  
+> *John told Mary he would meet her at noon.*
+
+If the future is indefinite, it will stays in the future, whether the event has
+happened or not.
+
+> 
+> he-nom.fi.sg believe-ind.pst.cont `<sub>` she-nom.ea.sg back-come-ind.fut.prf,
+> that-acc.sg she-nom.ea.sg do.ind.pst.prf  
+> *He believed she would come back, and she did.*
+
+### Narration
+
+Narration is always present tense, even when the story obviously happened in the past.
+
+## Mood
+
+- indicative: the action actually occurs
+- interrogative: the action is in the question
+- imperative: the action is a command
+- subjunctive: the action does not happens, and usually used in conditional or wish
+- ritual: the action is the intend of the spellcaster
+
+Ritual mood is also used for cursing and profanity.  In such case, the gender
+affix is removed so the speaker does not accidentally cast the actual curse.
+Because cursing is quite literal for Hàäsdáïga speakers, it is never used in
+the same manner as in the modern society.
+
+## Aspect
+
+- habitual: the action happens repeatedly in the period of time
+- continuous: the action or the state persists over the duration
+- perfective: the action happens once and finished

+When a component in the syllable is missing, the other components expand to
+fill up the gap.  Long vowel is represented as a horizontal line in the V2

+
+Because it requires more than a font to be able to write these glyphs, I cannot
+create a font to represent it.  There will be a tool to generate svg/png for
+generaating glyphs from a word, however.  All text samples in this book will be
+romanized, from which you can generate the native scripts.
+
+## Order
+
+Hàäsdáïga does not have an alphabetic order.
+The alphabet order is used for us to more conveniently list words.
+The order for letters with tones is level, falling, and rising.
+
+## Letters
+
+Letters used to form glyphs are listed in the table below:
+

+
+Punctuation usage:
+
+- Sentence punctuation `. ! ? :` are put at the beginning of the sentence,
+    rather than the end.
+- Colon is considered a sentence punctuation.  It is put at the beginning of
+    the quoted phrase.
+- Comma is used in a similar way as in English.
+- Brackets are used for both quotation and explanation. In case of quotation,
+    there should be a colon preceding the phrase.
+
+# Input for glyph generation
+
+While this is not a part of the language, in order to generate native script
+with the provided tool, one MUST follow this guideline for writing
+romanization, which is not the same as the normal romanization guideline.
+
+- If there is a tone, the schwa `y` must be explicit.  That is, never put the
+    tone on a consonant.
+- The second vowel should not come with the diaresis.
+- Long vowel should be represented by a tilde `~` rather than duplicating
+    vowels.
+- Always write syllables separately.  For example `càhánzy` (to give) must
+    be written as `cà hán zy`.
+- The glottal stop must be explicit.  For example `aäratse` (ash) must be
+    written as `'a~ rat se`.
+- Punctuations should be separated from syllables.
+- Spaces should be noted with a hyphen.
+
+The output may look bad; you can blame my poor drawing skills (I did not align
+some of the strokes) and the limitation of technology (the letters are
+stretched and therefore the thickness is not consistent).
