Yo My name is Li.And I have a dialect do you know what that means? Probably not.
No worries I am going to tell you.
I would say it revolves pretty much around your accent which is the way you speak a certain language and you accent makes words sound different to other when you literally mean the same word they know..
So basically a Dialect is a particular in which talk, sound and speak a language in order to express your self
Lets take me for instance I am a Chinese Kid, my first language is mandarin which is a language we speak back in my home town.
When I started learning English in school, my mandarin accent made me sound funny to kids who already knew how to speak English fluently.
