What does carpooled mean?
Carpooled is the past tense and past participle of the verb carpool, meaning to share a car journey with other people traveling to the same or nearby destinations, usually to save money on fuel, reduce traffic congestion, or lessen environmental impact. A typical carpool involves colleagues commuting to work together or parents taking turns driving children to school, often rotating the driving duties among members. The word carries practical, community-minded connotations and became widespread in American English during World War II, when fuel rationing made shared rides a patriotic necessity. Today it appears frequently in discussions of sustainability, urban planning, and workplace benefits such as designated carpool parking. In British English, similar arrangements are more commonly described as lift-sharing or car-sharing, though carpool is increasingly understood worldwide.

Etymology of carpooled
The compound carpool joins car, from Latin carrus via Old Northern French carre, with pool in its sense of a shared fund or collective arrangement, which developed in nineteenth-century American English (as in betting pools). The combined term arose in early twentieth-century America and spread widely during World War II fuel rationing. Its pool element is unrelated etymologically to swimming pool's sense of a body of water.
