'wrath' originates from Old English, specifically the word 'wrǣth' or 'wræth', and from Proto-Germanic '*wrathaz', where the stem meant 'angry' or 'wrath'.

'wrath' changed from Old English 'wrǣth/wræth' into Middle English 'wrath' and eventually became the modern English word 'wrath'.

Initially, it meant 'anger, being angry or revengeful'; over time it remained primarily 'intense anger' but broadened in literary and religious contexts to include the sense of 'divine punishment'.
