1363 (implied in trammeller) "net to catch fish," from M.Fr. tramail, from O.Fr. (c.1220), from L.L. tremaculum, perhaps meaning "a net made from three layers of meshes," from L. tri- "three" + macula "a mesh." It. tramaglio, Sp. trasmallo are Fr. loan-words. The verb is attested from 1536, originally "to bind up (a corpse);" sense of "hinder, restrain" is from 1727.
