 An alternative explanation is that from around the 13th century the local area was owned by the Colt family, sometimes known as Coats, and their estate generated place-names such as Coatbridge, Coatdyke, Coathill and Coatbank. Drummond and Smith suggest the name derives from the granting of land to Ranulphus le Colt around the time of the 12th century. However, Early Scots / ol / had vocalized to / o ̞ u / by the 16th century and subsequently diphthongised to / ʌu / in Modern Scots, so that 'Colt' would have become 'Cowt' rather than 'Coat'. Modern Scots'Cot' (cottage) is realized / kot /.
