'angry' originates from Old Norse, specifically the word 'angr', where the root meant 'grief; sorrow; affliction', later formed via the noun 'anger' plus the adjectival suffix '-y' (from Old English '-ig').

'angr' influenced Middle English through the noun 'anger'; Middle English 'angri/angry' developed and eventually became the modern English word 'angry'.

Initially, it meant 'full of sorrow; afflicted' or 'troublesome', but over time it shifted to its current meaning of 'wrathful; filled with anger'.
