Meaning and origin of Colin
Colin is a Scottish and English name that is usually said to mean “young dog; or a form of Nicholas”.
Colin has two separate origins. In Scotland it anglicizes the Gaelic Cailean, often linked to a word meaning "whelp" or "young dog", a name borne by chiefs of the Campbell clan. In medieval England, Colin was a diminutive of Colle, itself a short form of Nicholas, which comes from Greek elements meaning "victory of the people". Both routes produced a name that has been used for centuries. In the United States it is usually pronounced KAH-lihn, and in Britain KOL-in. Colin is friendly, dependable and understated, a classic that never feels stuffy.
Other spellings with the same sound: Kolin.
