Cainye prefers to derive words from compounding roots; but even then there is a maximum of three syllables. To take a noun, for example, and make it into a verb, is not something Cainye does—take bāgì meaning "grave", to derive a verb meaning "to dig a grave", Cainye just compounds "dig" and bāgì—since "dig" wungyò, would result in a four syllable word, the last syllable is removed—and we get wungbāgì.

Avoid compounding adverbs with verbs, dómkâuyo (quickly-run) is dumb, while dóm kâuyo is as intended. Adjectives, though, are free reign. Prepositions typically only compound to form more prepositions, and no other parts of speech.

Cainye does not like changing a words part of speech, like turning cányún "income" into "to earn an income" like agglutinativee languages do, with concatenative affixes. Instead, it can be compounded with a verb meaning "earn", but this is not simple prefixing, because the "earn" verb could be independent.

yúcányún (yúngon + cányún)

Cainye also inherited "bound components" from Phúkìming, which are one syllable words that cannot be used except in compounds, and they encode a wide range, for example: hâu is the BC for liquids, fluids, and things that flow, and from it Cainye gets the verb hâuhon "to flow", and the nouns hâulei "bodily fluids", and hâukei "fish."
