What Does the Name Mac Mean?

Mac is an English masculine given name whose established meaning is "son." It comes from Scottish Gaelic mac, "son," a word also found in Irish as mac and in Old Irish as macc. The element is best known as the patronymic prefix in Gaelic surnames: Mac or its shortened spelling Mc is attached to a father's or ancestor's name, as in MacDhòmhnaill, "son of Donald." As a given name, Mac usually functions as a short form of a longer Scottish or Irish name beginning with Mac-, such as Mackenzie or Macaulay, but it can also be used directly from the Gaelic word for "son." The literal sense is familial; later uses as a general nickname or familiar form of address are extensions rather than separate etymologies.

Mac Name History & Origins

The element behind Mac has been used in Gaelic-speaking Scotland and Ireland for centuries as a marker of descent. In medieval and early modern Gaelic naming, a man was often identified by his father's name with mac: Dòmhnall mac Aonghais meant "Donald son of Angus." When patronymics of this kind became fixed hereditary surnames, Mac- and its shortened spelling Mc- became common prefixes in names such as MacDonald, MacKenzie, and MacCarthy. The given name Mac developed from this same naming tradition, usually as a shortened form of a longer Scottish or Irish name beginning with Mac-. It has also been adopted directly as a brief masculine name in English-speaking countries, where the Gaelic word for "son" supplied its meaning. In North American English, mac has separately been used as a generic form of address for a man, especially one whose name is unknown; that usage is related to the name but is not its etymological source.
