köken: From gauchir (“to bend, dodge, warp”), a conflation of Old French gauchier (“to tread”) (from Frankish *walkijan, *walkan, cognate with English walk) + Old French guenchir (“to deviate”) (from Frankish *wenkijan (“to sway, falter”)). Gauche replaced the original Latin-derived word for "left", senestre, in the sixteenth century. Compare Walloon gåtche.
köken: From Middle Dutch scheyff, from Proto-West Germanic *skēf, from Proto-West Germanic *skaib, from Proto-Germanic *skaibaz ‘crooked, askew’, from Proto-Indo-European *skeh₂iwo-. Compare Latin scaevus (“left, clumsy”), Ancient Greek σκαιός (skaiós, “rude; brusque”), Latvian šķìbs (“crooked”). Cognate with German schief, Old English *sc(e)āf (in scāffōt (“splay-footed”)), Swedish skev.
tilted (relative to an upright orientation), leaning, askew · having an inclination, leaning, inclined [with illative ‘towards’] (an opinion or similar)
eş: vinossa
köken: Adessive plural of the root *kalte- with a possessive suffix. The root is of the same origin as kallas.
köken: From Old Norse skeifr, from Proto-Germanic *skaibaz (“crooked”), of disputed ultimate origin. Perhaps from the same source as *skeuhaz (“frightened, shy”). Another possibility is Proto-Indo-European *skeh₂iwos, the source of Latin scaevus (“on the left side”). See also Swedish skev, Dutch scheef, German schief (from Low German).
