brat

Early Modern English (c. 1500) slang term meaning "beggar's child".^[1] Possibly from Scots bratchet (“bitch, hound”). Another possibility is that it was originally a dialectal word, from northern and western England and the Midlands, for a "makeshift or ragged garment," from Old English bratt (“cloak”), which is from a Celtic source (Old Irish brat (“cloak, cloth”)). In the sense "characteristic of a confident and assertive woman", coined by English singer and songwriter Charli XCX in her 2024 album Brat.^[2]
