Expert

An expert is someone who knows a lot about a certain topic or thing. It's like if you really like bugs, and you study them a lot and learn a ton of information about them, then you could become an expert on bugs.

Experts are people that have studied, practiced, and learned a lot about something. For example, if you want to be an expert in playing the piano, you need to practice a lot and take lessons to learn all the different chords, keys, and techniques.

Experts are people that you can ask questions to and they will know the answer. They are like teachers, but they know even more about a specific thing than a normal teacher does.

Some experts might even write books, make videos, or do lectures to teach other people about their area of expertise. So, if you want to know a lot about something, find an expert and learn from them!
