what is a theses statement?
please give an example

It’s the writer’s opinion. It’s what the essay is about. In essays for school, it’s typically stated in a single sentence that is found in the latter part of the first paragraph. If you’re writing this theses statement, then each of your topic sentences should relate back to your theses statement.

If I’m writing an essay about my cat, then my theses statement might be: “I love my cat because he’s cute, friendly, and fun to play with.” Then I would go on and explain why I think he’s so cute, why I think he’s friendly, and why he’s fun to play with. This is a very simplistic example, but I hope you get the idea.
