Etymology

From Middle English lesioun (“physical injuring of the body”), from Old French lesion (“hurt, offense, wrong, injury, wound”), from Latin laesiō (“hurt, harm, injury”) (whence -ion (“noun suffix denoting action, result, process, state, condition”)), from laesus (“hurt, injured, wounded, damaged”), past participle of laedō (“to strike, collide, hurt”).
