Colin, pronounced KAH-lin, traces a twin lineage: on one branch it descends from the Scottish-Gaelic Cailean, “young pup” or “whelp,” a term once bestowed on fresh-faced warriors; on the other, it slips in from medieval France as a pet form of Nicolas, quietly carrying the meaning “victory of the people.” The name moves through history rather like saffron threads in a Persian rice dish—subtle yet unmistakable—appearing in literature, borne by saints such as sixth-century Columba, and, in modern times, lent an urbane sheen by actors Colin Firth and Colin Farrell. In the United States its popularity crested in the early 2000s before settling into a comfortable middle rank, suggesting a balance between familiarity and individuality. For parents, Colin offers a compact, two-syllable choice: easy on the ear, modestly heroic in heritage, and touched with just enough Old-World romance to feel at home whether whispered in a Scottish glen or, dare one imagine, recited over cardamom tea in Shiraz.
