surname, from Gaelic Maolagan, Old Irish Maelecan, a double diminutive of mael "bald," hence "the little bald (or shaven) one," probably often a reference to a monk or disciple. As "stew made with whatever's available" (1904) it is hobo slang, probably from the proper name. The golf sense of "extra stroke after a poor shot" (1949) is sometimes said to be from the name of a Canadian golfer in the 1920s whose friends gave him an extra shot in gratitude for driving them over rough roads to their weekly foursome at St. Lambert Country Club near Montreal.

"on a small scale, much reduced from natural size," 1714, from miniature (n.). Of dog breeds, from 1889. Of golf played on a miniature course, from 1893.
