Mail Names Letters and Also Armour

Mail is the postal system. A separate mail is the interlinked metal rings of medieval armour.

Mail is the postal system and the letters it carries, and also a type of armour made from interlinked metal rings. The two are unrelated. The postal sense comes from Old French *male*, a travelling bag โ€” the bag named its contents. The armour is from French *maille*, a mesh, from Latin *macula*, a spot or mesh of a net. *Chain mail* is a modern term; medieval writers said simply *mail*, since the rings were the whole point.
