charwoman: [16] A charwoman is, quite literally, a woman who does ‘chores’. Chore is a variant of the now obsolete noun chare or char, which meant literally ‘turn’ (it derived from the Old English verb cerran, which may be the source of charcoal). Hence ‘doing one’s turn’, ‘one’s turn at work’ in due course advanced its meaning to ‘job’. Already by the 15th century it had connotations of menial or household jobs: ‘making the beds and such other chares’, Nicholas Love, Bonaventura’s Mirror 1410. => ajar, chore
