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

'tēman' transformed into the Middle English word 'temen,' and eventually became the modern English word 'teem.'

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