One thing I’ve been working on lately is to figure out how the Kasshi themselves analyze their language, as opposed to how it would be analyzed in the Western tradition. I’ve figured out their equivalents of parts of speech. They recognize six major parts (I’m not sure of the native names yet)
Nominals (nouns, adjectives, pronouns)
Unchanging words (uninflected words, i.e., prepositions, conjunctions, etc.)
Auxilaries in Kasshian are suffixed to verbs, which is why they’re classified as a separate class, rather than being seen as a type of verb. Gender-markers are prefixes in Classical Kasshian, but in some related languages are free-standing words that go in front of noun phrases.
Inflections are referred to by a term meaning literally “changes”.
Nominals are further subdivided into three subtypes
Independent nominals are nominals with a fixed gender, while agreeing nominals are nominals without a gender of their own, that is, adjectives plus certain body parts whose gender “agrees with” their possessor. For example, the word for “head” has no fixed gender, being, for example, gender I (female sentient) if you’re referring to a woman’s head, gender II (male sentient) for a man’s head, gender IV (domestic animals and other animals associated with people) for, e.g., a cat’s head, and so on. Including metaphorical uses, it can therefore be any gender. On the other hand, the word for “arm” is always gender VI no matter whose arm you’re talking about, and is thus an independent nominal.
The “Pronoun” subclass is only for free pronouns, and does not include the clitic forms, which are included in the Attacher category.
