'teem' originates from Old English, specifically the word 'tēman,' where 'tēman' meant 'to bring forth or produce.'

'tēman' changed from the Old English word 'tēman' and eventually became the modern English word 'teem'.

Initially, it meant 'to bring forth or produce,' but over time it evolved into its current meaning of 'to be full of or swarming with.'
