(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 and Scottish: from the Breton personal name Aeruiu or Haerviu, composed of the elements haer ‘battle’, ‘carnage’+ vy ‘worthy’, which was brought to England by Breton followers of William the Conqueror, for the most part in the Gallicized form Hervé. (The change from -er- to -ar- was a normal development in Middle English and Old French.) Reaney believes that the surname is also occasionally from a Norman personal name, Old German Herewig, composed of the Germanic elements hari, heri ‘army’ + wīg ‘war’.
Irish: mainly of English origin, in Ulster and County Wexford, but sometimes a shortened Anglicized form of Gaelic Ó hAirmheadhaigh ‘descendant of Airmheadhach’, a personal name probably meaning ‘esteemed’. It seems to be a derivative of Airmheadh, the name borne by a mythological physician.
