Words in Apatani, as in other languages, are formed by putting together morphemes.

Morpheme is a meaningful linguistic unit consisting of a word, such as man, or a word element, such as -ed in walked, that cannot be divided into smaller meaningful parts (American Heritage Dictionary). As such morphemes in Apatani are in form of words (aya, kaaru, miyu,  nii, whu etc.), verb roots (aa, dii, ka etc.,) and affixes (-ne, -do, -ma, -kindo, -kinma, -pa, -pyo, -pyow etc.).
