Etymology
The word 'ventilator' has a clear lineage from the Latin ventus, meaning 'wind'. The verb ventilare was formed, meaning 'to fan, winnow, or expose to the air', capturing the action of creating a current of air. The agent noun suffix -ator was then added to create ventilator, literally 'a thing that creates a wind or air flow'. This logical progression from the ancient concept of wind to a modern device for air circulation or assisted breathing perfectly illustrates how morphemes combine to build precise technical meanings.
