With nobody standing against you. It turns up most often in elections and politics: if a candidate is unopposed, no other person is running for that job, so they simply win. Newspapers love the phrase 'elected unopposed' or 'ran unopposed'. It also stretches to any situation where a plan, an idea, or an army meets no resistance — a motion passes unopposed at a meeting because nobody voted against it; soldiers march in unopposed because no one fights back. The word works both as an adjective ('an unopposed candidate') and as an adverb-like word after a verb ('she won unopposed'), which is unusual and worth noticing. There is a quiet feeling attached to it that dictionaries do not always mention: winning unopposed sounds a little hollow. If your teacher says you were elected unopposed, the compliment is smaller — you did not beat anyone, you were just the only one there. In sport commentary you may hear 'unopposed' used loosely for a player with no defender near them, though 'unmarked' is the usual football word.
