oponente
/opoˈnente/ · B2 · adj
opponent
🥊 o- + ponente, from Latin ponere 'to place' → one placed against you
Oponente comes from Latin opponere: ob- 'against' + ponere 'to place'. An opponent is someone placed against you. English 'oppose' and 'opponent' come from the same root, so the link is direct.
