Not completed or lacking a final touch; something that is still in progress or not fully developed.
The artist left the painting unfinished, hoping to return to it later.
Unfinished → It is formed from "un-" (meaning not) and "finished" (from Old French *finir*, meaning to end or complete). The word "unfinished" means not completed or lacking an end.
Think of something that is 'not' ('un-') 'completed' ('finished') — that's why unfinished means it hasn't reached its end.
