adjective conspicuously or grossly unconventional or unusual
originBorrowed from French bizarre (“odd, peculiar, bizarre”, formerly “headlong, angry”), then either from Italian bizzarro (“weird, eccentric, frisky”) or, less likely, from Basque bizar (literally “beard”, from the notion that bearded Spanish soldiers made a strange impression on the French).
