ORIGIN & HISTORY

About the name

Alistair is the Anglicized spelling of the Scottish Gaelic name Alasdair, which is itself the Gaelic form of Alexander. Because of this chain, its traditional meaning of 'defender of men' is inherited from the Greek name Alexandros rather than being a direct etymology of the Alistair spelling.

Alasdair (Scottish Gaelic). "Defender of men", a meaning inherited from Greek Alexandros (alexo "to defend" + aner "man") via the Alasdair/Alexander name chain, rather than derived directly from the English spelling Alistair. Alistair developed as an English spelling adaptation of the Scottish Gaelic name Alasdair, part of the wider Alexander name family that spread through Europe in connection with Alexander the Great. The chain runs from Greek Alexandros through Latin Alexander and Old French Alixandre before being adopted into Scottish Gaelic as Alasdair, which was in turn commonly Anglicized as Alistair, Alastair, and Alaster.
