mitten

mitten: [14] Etymologically, a mitten is ‘half a glove’. The word comes via Old French mitaine from Vulgar Latin *medietāna ‘cut off in the middle’ (originally an adjective, and applied to gloves, but subsequently used independently as a noun meaning ‘cut-off glove’). This in turn came from Latin medietās ‘half’ (source of English moiety [15]), a derivative of medius ‘middle’ (source of English medium). The abbreviated mitt dates from the 18th century.
=> medium, moiety

mitten (n.)

late 14c., from Old French mitaine "mitten, half-glove" (12c.), from Old French mite "mitten," and from Medieval Latin mitta, which are perhaps from Middle High German mittemo, Old High German mittamo "middle, midmost" (reflecting notion of "half-glove"), or from Vulgar Latin *medietana "divided in the middle," from Latin medius (see medial (adj.)).
