'rage' originates from Old French, specifically the word 'rage', which derived from Latin 'rabies' meaning 'madness, fury'.

'rage' came into English from Old French 'rage'; the Latin root 'rabies' (meaning 'madness, fury') influenced the Old French form, and through Middle English it became the modern English word 'rage'.

Initially, it meant 'madness' or violent fury (closely linked to the idea of rabies), but over time it evolved to mean 'violent anger' and also developed a separate sense of 'a popular craze'.
