KK: /ˈoʊvərˌzil/
A strong and excessive enthusiasm or eagerness for something, often leading to overexertion or extreme actions.
His overzeal in promoting the project caused some team members to feel overwhelmed.
Overzeal → It is formed from "over-" (meaning excessively) and "zeal" (from Old French *zel*, meaning fervor or enthusiasm). The word "overzeal" means excessive enthusiasm or fervor beyond what is reasonable.
Think of being 'excessive' ('over-') in your 'enthusiasm' ('zeal') — that's why overzeal means having too much enthusiasm.
