Synonym Chooser

How is the word fantastic different from other adjectives like it?

The meanings of bizarre and fantastic largely overlap; however, bizarre applies to the sensationally strange and implies violence of contrast or incongruity of combination.

Although the words grotesque and fantastic have much in common, grotesque may apply to what is conventionally ugly but artistically effective or it may connote ludicrous awkwardness or incongruity often with sinister or tragic overtones.
