What is the opposite of peerless?

The opposite of peerless depends on context, but generally means having equals or being inferior, common, or mediocre. Peerless means without peer, without equal, having no rival, being the best, unique, or unmatched in quality. It comes from peer meaning equal and less meaning without, so without equal. Therefore, the opposite would be words that mean having many equals, being common, or being inferior. The most direct antonyms include mediocre, common, ordinary, average, run-of-the-mill, second-rate, inferior, and unexceptional. If peerless means the best with no equal, its opposite is the worst or merely average with many equals. For example, if a peerless performance is outstanding and unmatched, the opposite would be a mediocre or forgettable performance. Other antonyms include flawed, imperfect, and comparable. In a ranking context, peerless means top-tier, so opposite could be bottom-tier. In quality terms, if peerless means superb and supreme, opposites include poor, subpar, and undistinguished. The word peerless is always positive, describing something exceptional like a peerless diamond or peerless beauty, so any word describing something ordinary or having many equals is an antonym. So the best single-word opposites are mediocre, ordinary, and inferior, while the phrase opposite would be having many peers or nothing special.
