Definition: to remain loyal to a person or thing; to continue a behavior or continue using a service.

How to use it: This is an inseparable verb. The words must be used together. If you change the order then you change the meaning of the verb (to stick someone with something has a different meaning).

Examples:

• I'm going to stick with this cell phone company for awhile. I can't find anything better.
• "I know you haven't lived here very long. Stick with me and I'll show you the town. You'll feel like a native in no time."
