Note 91 — V Form in Language: Grammatical Concepts

Footnote 91: In Yana the noun and the verb are well distinct, though there are certain features that they hold in common which tend to draw them nearer to each other than we feel to be possible. But there are, strictly speaking, no other parts of speech. The adjective is a verb. So are the numeral, the interrogative pronoun (e.g., “to be what?”), and certain “conjunctions” and adverbs (e.g., “to be and” and “to be not”; one says “and-past-I go,” i.e., “and I went”). Adverbs and prepositions are either nouns or merely derivative affixes in the verb.
