Speaks in a loud, aggressive, or bullying way; or noisy, violent bursts of wind or loud talk.
From Middle Low German 'blusteren,' meaning to blow violently or talk noisily. Related to Old Norse 'blāstr' (blast). The word evolved from describing physical wind to describing loud, aggressive speech.
Bluster is a fascinating defense mechanism—when someone blusters, they're often trying to seem more confident or threatening than they actually feel, which is why blustery people often back down when challenged. It's like verbal puffing-up!
