Imagine that you're supposed to wash the dishes, but you don't want to. You want to watch a video on the Internet instead. Someone in your family reminds you several times to wash the dishes. You might think that this family member is "nagging" you.
The word "nagging" is a negative way to describe reminding a person of something that they're supposed to do.
Family members, couples, and roommates sometimes "nag" each other about things like:
- doing household chores
- paying bills
- calling family members
