1. To assist or provide something to a person or business. As a personal assistant, I cater to busy professionals who need help managing their lives.

2. To give special treatment or consideration to someone, perhaps to an excessive degree. They're our biggest account, so we usually end up catering to them to make sure they're completely satisfied with the service. My sister has been catering to my every whim ever since I caught her sneaking in past curfew.
