Tam-o'-shanter is a type of Scottish woolen cap usually worn by men. It is also commonly referred to as a Balmoral bonnet or simply a tam. The term Tam-o'-shanter is derived from a character in a popular poem by Scottish poet Robert Burns. Synonyms for Tam-o'-shanter include beret, cap, beanie, skullcap, and hat. Berets are usually made of wool, felt, or velvet and are flat-crowned. Caps are brimless head coverings made of different materials, while beanies are knitted hats that fit snugly on the head. Skullcaps are a type of tight-fitting hat that is usually worn by men of the religious Jewish community. Hats, on the other hand, refer to any head coverings that are worn on the head.
