To oppose something is to disagree with it strongly and try to stop it or act against it.
From Latin “opponere” meaning “to set or place against,” from “ob-” (against) and “ponere” (to put, place). Through Old French, it came to mean actively resisting or confronting.
To ‘oppose’ is literally to ‘place yourself against’ something, like standing in front of a moving object. That image shows why opposition is powerful: it turns a passive “I don’t like this” into a physical, blocking stance.
