+# Negation
+
+To negate a sentence, simply put the negative adverb in front of the verb.
+For each sense of negativity, there is a separate word:
+
+- not: kèë
+- not yet: niï
+- never: chon
+
+Following are the opposite of them: 
+
+- yes: daä
+- already: voc
+- always: réïn

+# Question
+
+The preferred word orders are discussed in previous sections.  Verbs must be
+used in interrogative mood.
+
+One may have noticed in the Sentence order section that yes/no questions are
+formed by adding a negative adverb at the end of the sentence.  Here are two
+examples with *niï* and *chon*:
+
+>
+> *Have you ever been to the capital?*
+>
+>
+> *Do you really never eat meat?*

+# 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.*
