opposing
UK: əˈpəʊzɪŋ | US: əˈpoʊzɪŋ
adj. acting against or resisting something
v. (present participle of oppose) to disagree with or resist something
The word opposing derives from Latin opponere (to place against), combining ob- (against) and ponere (to place). Over time, opponere evolved into Old French opposer, then Middle English opposen, eventually becoming oppose in Modern English. The suffix -ing turns the verb into a present participle or adjective, maintaining the core idea of "acting against."
