Gael \gael\ as a girl's name (also used as boy's name Gael), is of Gaelic origin, and the meaning of Gael is "a Celt". The term was first used in English to refer to the Highland Celts of Scotland. Over time it has also come to mean the Irish. Before it came into English, Gael was a self-descriptive term used by both Scots and Irish. The Scots term "Gaidheal" probably evolved from the Irish "goidel", which may be traced back to the Old Celtic word "gwydd", meaning "wild".
