Alistair

Alistair is a male given name. It is an anglicised form of the Scottish Gaelic Alasdair. The latter is most likely a Scottish Gaelic variant of the Norman French Alexandre or Latin Alexander, which was incorporated into English in the same form as Alexander. The deepest etymology is the Greek Ἀλέξανδρος (man-repeller): ἀλέξω (repel) + ἀνήρ (man), "the one who repels men", a warrior name. Another, not nearly so common, Anglicization of Alasdair is Allaster.
