Synonym Chooser

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

The words bizarre and grotesque are common synonyms of fantastic. While all three words mean "conceived, made, or carried out without adherence to truth or reality," fantastic may connote extravagance in conception or ingenuity of decorative invention.

When is it sensible to use bizarre instead of fantastic?

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

Where would grotesque be a reasonable alternative to fantastic?

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.
