'impassioned' originates from the prefix 'im-' meaning 'in' and the word 'passion', which comes from Latin 'passio', meaning 'suffering' or 'feeling'.

'impassioned' evolved from the Middle English word 'passiouned', which was influenced by the Old French 'passioné'.

Initially, it meant 'filled with passion or suffering', but over time it evolved into its current meaning of 'filled with or showing great emotion'.
