the.com/maid

means A woman employed to clean and keep house, or, in older use, an unmarried girl or young woman.

from A shortening of 'maiden,' from Old English 'mægden,' going back to a Germanic root for 'young woman' or 'virgin.' The word first meant simply a girl or unwed young woman — Shakespeare's 'fair maid' — and only later narrowed, via domestic service, into the job title. 'Old maid' and 'maiden name' preserve the original, pre-job sense.
