bizarre

\ \ [17] Bizarre can probably be traced back to Italian bizzarro, of unknown origin, which meant ‘angry’. It passed into Spanish as bizarro, meaning ‘brave’, and then found its way into French, where its meaning gradually mutated from ‘brave’ to ‘odd’ – which is where English got it from. It used to be thought that the French word might have come from Basque bizarra ‘beard’ (the reasoning being that a man with a beard must be a brave, dashing fellow), which would have made bizarre almost unique as a word of Basque origin in English (the only genuine one in everyday use now is the acronymic name ETA, standing for Euzkadi ta Azkatasuna ‘Basque Homeland and Liberty’), but this is now not thought likely.
