Studying the difference between comma, semicolon, and period. Would love some examples of when to use each?

a period is used at the end of a sentence. A coma is used when you are listing something, and a semicolon is used when you have two sentences or statements combined into two.
a period is used at the end of a sentence. For example: The cat was in the tree. This is just one solid statement.
A comma can be used when you are listing something. For example: For lunch I had a sandwich, an apple, and a juice box.
A semicolon can be a bit more difficult to use. It is used to separate two sentences without a period. For example: I have a big test tomorrow; I can’t go out tonight. are used to separate two separate statements.
