• Synonyms Wonderful, Strange, Surprising, Curious, Unique, extraordinary, marvelous, amazing, startling, wondrous (poetic). Wonderful generally refers to something above the common, and so marvelous, perhaps almost incredible. Strange refers rather to something beside the common—that is, simply very unusual or odd, and so exciting surprise or wonder. Anything that excites awe or high admiration, or strikes one as sublime, is wonderful; an unpleasant object may be strange, but would not be called wonderful. That which is unexpected is surprising, but it is not necessarily strange; as, a surprising fact; a surprising discovery in science. Curious is wonderful on a small scale; by its derivation it often refers to an object extremely nice and intricate or elaborate in itsdetails, but also it oft en conveys thenotion of pleasing strangeness and even of rarity: as, a curious bit of mosaic; a curious piece of mechanism; a curiously colored stone. Unique expresses that which is sole of its kind or quality: as, a unique book; a unique sort of person. See eccentric and surprise.
