manacle

The noun is derived from Middle English manacle, manakelle, manakil, manakyll, manicle, manikil, manycle, manykil, manykle, from Anglo-Norman manicle, manichle (“gauntlet; handle of a plough; (in plural) manacles”), and Middle French manicle, Old French manicle (“armlet; gauntlet; (in plural) manacles”) (modern French manicle, manique (“gauntlet”)), from Latin manicula (“handle of a plough; manacle”), from manus (“hand”) (ultimately from Proto-Indo-European *(s)meh₂- (“to beckon, signal”)) + -cula (from -culus, variant of -ulus (suffix forming diminutive nouns)). The verb is probably derived from the noun, although according to the Oxford English Dictionary it is attested slightly earlier.
