Can you use a semicolon at the end of sentence?

No, you should not use a semicolon at the end of a sentence.

A semicolon is used to connect two independent clauses that are closely related in meaning. It acts as a stronger pause than a comma, but not as strong as a period.

Here's an example:

* Correct: I went to the store; I needed to buy groceries.

* Incorrect: I went to the store;

The semicolon needs another independent clause to function correctly.
