Her enthusiasm for the project was unwaning, even after many challenges.
Unwaning → It is formed from "un-" (meaning not) and "waning" (from Old English "wanian", meaning to decrease or diminish). The word "unwaning" means not diminishing or decreasing, often used to describe something that remains constant or unchanging.
Think of 'not' ('un-') decreasing ('waning') — that's why unwaning means something that does not diminish.
