If your mom announces “We’re taking a cruise!” then pack your bags. A cruise is a vacation spent on a ship that sails the ocean, periodically stopping in ports for sightseeing.
Cruise can also be a verb that describes sailing around aimlessly for fun. You might cruise the canals of Venice in a small boat. If you don’t live in Venice, you can still cruise — but you might do it in your car. Cruise can be used to describe a leisurely drive taken just for fun. You might cruise around the neighborhood on a Saturday with no real destination in mind. Cruise can also describe traveling easily at a moderate speed.
