yooznah

Navajo

Etymology

yi- (thematic) + -oo- (combining form of an unidentified yi- prefix) + -Ø- (3rd person subject prefix) + -Ø- (classifier) + -nééh (imperfective stem of root -NAH, “to forget”).

This verb appears to have two yi- prefixes of unidentified origin, contracting as yi-₁ + yi-₂ = yoo-. That there are actually two yi- prefixes is more clearly visible in the future:

yi-₁ + di-_FUT + yi-₂ + ee-_FUT + sh-_1sg + -nah = yidiyeeshnah.

Verb

yooznah

(with baa) he/she forgot about it
