What is a nerd?
A nerd is just a slang term for a person with a great interest in one or more subjects. And that person could be a boy or a girl.
But if you Google the word "nerd" you might find a defnition like this: a nerd is a person, properly a man, who is not attractive. He might be awkward or socially embarrassing. This is how it used to be, but that's not the truth anymore.
A nerd can be anybody (like you and me) with a great interest in subjects like sicence, art, politics, yoga, sports, cooking or something completely different!
So, if you are a nerd, whether you are male, female or transgender, just be proud of that!
