Complaisant is an adjective that means willing to please others.

The Latin word complacere (com pla SER ay) means ‘to please.’ In addition to our word of the day, it has given birth to words like complacent and comply. Complaisant is often used to describe a person’s temperament. Example:

Mike’s complaisant demeanor makes him a great bartender. But at the same time, being so eager to please didn't make him a great prison guard.
