Synonym Usage
Oppose, resist, withstand imply setting up a force against something. The difference between oppose and resist is somewhat similar to the one between offensive and defensive action. To oppose is mainly to fight against, in order to thwart, certain tendencies or procedures of which one does not approve: The lobbyists opposed the passage of the bill. Resist suggests that the subject is already threatened by the forces, or by the imminent possibility, against which they struggle: Our religion requires us to resist temptation. Whereas oppose always suggests an attitude of great disapproval, resist may imply an inner struggle in which the will is divided: She tried unsuccessfully to resist her craving for ice cream. Withstand generally implies successful resistance; it may refer to endurance that allows one to emerge unharmed ( to withstand a shock ), as well as to active resistance: The fort should be able to withstand an aerial attack.

Etymology
Origin of oppose
First recorded in 1350–1400; Middle English, from Old French opposer, blend of Latin oppōnere “to set against” and Old French poser “to pose, place,” associated with the Latin past participle oppositus; see pose 1
Explanation
To oppose something is to go against it or fight hard to stop it. A senator might oppose a bill, or a teen might oppose authority. Words starting with opp-, like opposite, opponent, and oppose, usually hint that there's a disagreement somewhere. You might oppose a decision if you don't agree with it or if it's the opposite of what you believe or know is right. Sometimes, though, to oppose just means to be on the other team.
