A sur coat is a type of outer garment that originated in medieval times and was worn over armor. Synonyms for sur coat include tabard, tunic, mantle, cloak, and cape. Each of these terms refers to a similar type of garment, but with slight differences in style or function. For example, a tabard typically features a square shape, while a tunic is longer and covers the hips. A mantle is a type of cloak that covers the shoulders and upper body, while a cloak and a cape are both large, flowing garments that can be used for warmth or for dramatic effect in theatrical performances.
