Synonym Usage

Bizarre, fantastic, grotesque, weird share a sense of deviation from what is normal or expected. Bizarre means markedly unusual or extraordinarily strange, sometimes whimsically so: bizarre costumes for Mardi Gras; bizarre behavior. Fantastic suggests a wild lack of restraint, a fancifulness so extreme as to lose touch with reality: a fantastic scheme for a series of space cities. In informal use, fantastic often means simply “exceptionally good”: a fantastic meal. Grotesque implies shocking distortion or incongruity, sometimes ludicrous, more often pitiful or tragic: a grotesque mixture of human and animal features; grotesque contrast between the forced smile and sad eyes: a gnarled tree suggesting the figure of a grotesque human being. Weird refers to that which is mysterious and apparently outside natural law, hence supernatural or uncanny: the weird adventures of a group lost in the jungle; a weird and ghostly apparition. Informally, weird means “very strange”: weird and wacky costumes; weird sense of humor.

Etymology

Origin of bizarre

First recorded in 1640–50; from French: “strange, odd,” from Italian bizzarro “quick to anger, choleric,” then “capricious,” then “strange, weird”; further origin disputed

Explanation

Someone or something bizarre is odd or unusual in appearance, style, or character. If your teacher walks into class wearing a purple boa, lime-green cowboy boots, and a scuba mask, you might comment, "How bizarre!" Things that are bizarre often involve strange contrasts or unexpected elements. Bizarre was borrowed from French, from bizarro "angry, fierce, strange," from Spanish, "bold, like a knight." The Spanish word was probably influenced by Basque bizar "a beard," since beards were taken as signs of energy and spirit. Nowadays it takes more than a beard to get you labeled as bizarre. Unpredictable behavior is often called bizarre — like when your little brother decides that he will communicate only in Pig Latin.
