'shower' originates from Old English, specifically the word 'scūr', where 'scūr' meant 'a short fall of rain'.

'scūr' transformed into the Middle English word 'shour', and eventually became the modern English word 'shower'.

Initially, it meant 'a short fall of rain', but over time it evolved to include the modern meanings of 'a device for washing' and 'to give abundantly'.
