Etymology

Origin of ancilla

First recorded in 1870–75; from Latin: literally, “handmaid,” diminutive of ancula “maid,” from unrecorded anquola, equivalent to an-, a variant of ambi- “around” + -quola, noun derivative of the root kwel-, kwol- “turn about,” hence “one who circles around”; cognate with Greek amphípolos “attendant”; see origin at ambi-, amphi-, ancile
