Oxtail → The word is formed from "ox" (from Old English "oxa", meaning a castrated male bovine) and "tail" (from Old English "tægel", meaning the appendage at the rear of an animal). Oxtail refers specifically to the tail of an ox, which is often used in cooking.
Think of the Old English word for a castrated male bovine ('ox') and the appendage at the rear ('tail') to remember that oxtail is the tail of an ox.
