Barkeep → The word is formed from "bar" (from Old French *barre*, meaning a barrier or counter) and "keep" (from Old English *cepan*, meaning to take care of or to hold). A barkeep is someone who takes care of or serves drinks at a bar.
Think of a 'bar' as a counter where drinks are served, and 'keep' means to take care of something. So, a barkeep is someone who takes care of the bar.
