 # 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:
+
+- (be)
+- (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.
+
+> this-nom.sg be.ind.prs.hab book-nom.wo.sg I-gen.ea.sg  
+> *This is my book.*
+> 
+> this-nom.wo.sg book-nom.wo.sg be.ind.prs.hab I-gen.ea.sg  
+> *This book is mine.*
+
+*Relations* also include relations constructed by postposition.
+
+> he-nom.fi.sg stay-ind.fut.prf with I-gen.wa.sg  
+> *He will stay with me.*
+>
+> stand-ind.prs.cnt man-nom.sg (in front of) shop-gen.ea.sg  
+> *There is a man standing in front of the shop.*
+
+## 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
