The Story of Alastair
Alastair is the Scottish Gaelic form of Alexander, which derives from the ancient Greek Alexandros, composed of alexein (to defend) and aner (man), meaning defender of men. It was the name of Alexander the Great, and the Scottish Gaelic adaptation Alastair has been used in the Highlands for centuries as an alternative to the Latinized Alexander.
Alastair has been a steady presence in Scotland and among Scottish diaspora communities. In England and the US it is considered a distinguished, slightly aristocratic name. The BBC journalist Alastair Campbell brought the name to wider prominence in the early 2000s.
Alastair represents a distinctly Scottish take on one of history's most storied names. In Highland Scottish culture, preserving Gaelic forms of names like Alastair (alongside Alistair and Alisdair) is a point of cultural pride and identity.
