Old English tēman, tīeman, of Germanic origin; related to team. The original senses included 'give birth to', also 'be or become pregnant', giving rise to 'be full of' in the late 16th century
Do not confuse team with teem. Team means 'a group of people working or playing together' or 'come together as a team to achieve something' (the two governors teamed up against their opponent), whereas teem means 'be full of something' (the seas teemed with fish).
