A person who uses a broom or besom to sweep; one who cleans with a broom.
From 'besome' or 'besom' (Old English 'besma'), a bundle of twigs bound together for sweeping, plus the agent suffix '-er'. The word evolved from Germanic roots meaning to bind or bundle.
The word 'besom' is so old that it appears in Shakespeare, and calling someone a 'besom' became a British insult—imagine being so associated with lowly sweeping that your job became an insult to your character!
