conceited

Conceited people tend to think they're better or more important than others.

The word "conceited" often pops up when we talk about someone who has a big ego. You might hear it used to describe someone who always talks about themselves and their achievements, like they're the best thing since sliced bread. They might brag about their wealth, looks, or talents, which can be annoying to those around them. On the other hand, sometimes people use "conceited" to mean someone who is overly confident in a way that's just plain rude. For example, if your friend always says things like "I'm going to be a superstar someday," but they have no actual talent or skills, you might call them conceited.
