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

'scūr' changed from Old English to 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 into its current meaning of 'a brief period of rain or a bath under a spray of water'.
