Etymology

The word prolate comes from the Latin prolatus, meaning 'stretched forward', from pro- 'forward' and latus 'carried', and you can link it to prolong ('make longer') as a memory help. So a prolate shape is one that is stretched or longer in one direction, like an egg or an American football.
