Meaning & History
Alastair is a Scottish masculine given name, an Anglicized form of the Scottish Gaelic Alasdair, which itself is a Gaelic adaptation of Alexander.
Etymology
The name ultimately derives from the Greek Ἀλέξανδρος (Alexandros), meaning "defending men" — from ἀλέξω (alexo, "to defend, help") and ἀνήρ (aner, "man", genitive ἀνδρός). In Greek mythology, Alexandros was an alternate name of Paris, prince of Troy. The most famous historical bearer is Alexander the Great, king of Macedon, who built a vast empire in the 4th century BC. His fame spread the name throughout Europe.
History and Usage
Alastair is the most common Anglicized spelling in Scotland, alongside Alistair and Alister. While the name Alexander has been borne by kings, emperors (e.g., three Russian emperors), and eight popes, Alastair remains distinctively Scottish. The Gaelic original Alasdair has been used in Scotland for centuries, with Alastair appearing as its English-equivalent form.
