(male) English form of a common biblical name (meaning ‘who is like God?’ in Hebrew) borne by one of the archangels, the protector of the ancient Hebrews, who is also regarded as a saint of the Catholic Church. In the Middle Ages, Michael was regarded as captain of the heavenly host (see Revelation 12:7–9), symbol of the Church Militant, and patron of soldiers. He was often depicted bearing a flaming sword. The name is also borne by a Persian prince and ally of Belshazzar mentioned in the Book of Daniel. Since the early 1900s it has been one of the most enduringly popular boys' names in the English-speaking world. See also Michal.

English: of much discussed but uncertain origin. 1. It may be from a medieval personal name, but if so the form is unclear. 2. Alternatively, it may be a nickname for a quarrelsome or deceitful person, from Middle English bar(r)et(t)e, bar(r)at ‘trouble’, ‘strife’, ‘deception’, ‘cheating’ (Old French barat ‘commerce’, ‘dealings’, a derivative of barater ‘to haggle’).
It is possible that the original sense of barat survived unrecorded into Middle English as a word for a market trader; the Italian cognate Baratta has this sense. It could also be a nickname or metonymic occupational name from Old French barette ‘cap’, ‘bonnet’.
