Hey!
A simple sentence is a sentence that is made up of 1 independent clause.
Example: I am a human.
A complex sentence is made up of 1 independent clause AND 1 or more subordinate clauses.
Example: Because I did my homework, I had an A in the class.
A compound-complex sentence is made up of 2 or more independent clauses and 1 or more subordinate clauses.
Example: Although I like reading books, I haven't read any this summer, and I don't think I have time to.
A compound sentence is made up of 2 independent clauses.
Example: I like reading books, and I also like taking pictures.
I hope you find this useful :)
