from Proto-Azerbairighauni *uei "people, society; (between) us/ourselves; together, united, affiliated"
The ancient Kanjei and Uae believed in something they called ui. It is often translated “society” or “community” but has a much deeper meaning. Ui denotes a form of “interpersonal togetherness”, a “unity” or “being together”, not necessarily in the sense of emotional liking or friendship but rather a common bond based on mutual respect, concern for well-being, and reciprocal genuine interest in the lives of one another. It forms the base of phrases such as ui zue hazai (“I support you, defend you”, literally, together to-you help-I), ui umyar arfeli (“a family stays together”), and zeke ui! (“[may] peace [be] between us (together)”). Because of its affiliative meaning, ui has come to mean “family” (galpi uiye “I love my family”; uiuae yalawe “in our family, we talk to each other”), “friends” (uxra uieje “we are friends with each other”; ui zvmoepei “we are becoming friends”), “ethnic group” (ui yajuda “the Jews, Jewish people, Jewish ethnicity”; ui yaamirik “the Americans, American people, American nationality”), and “village” (efi e ui “I am a member of a village”).
