Alasdair
Alasdair is a masculine given name, the Scottish Gaelic form of Alexander. Alexander originates from the Greek Alexandros, commonly interpreted as "defender of men" or "protector of mankind." In Gaelic usage, Alasdair is a traditional form used in Scotland and among Gaelic-speaking communities; in English contexts the name appears in variants such as Alastair and Alistair, with Alasdair maintaining closer ties to the original Gaelic spelling. The name has been borne by writers, philosophers, and historical figures, and remains in use in modern Scotland and abroad, often among people with Gaelic heritage.
