Here's why:
* Semicolons connect two independent clauses. An independent clause is a complete thought that can stand alone as a sentence.
* Sentence fragments are incomplete thoughts. They lack a subject or verb, or both.
Example:
* Correct: *The storm raged; the house shook violently.* (Both parts are complete sentences)
* Incorrect: *The storm raged; the roof leaking.* (The second part is a sentence fragment because it lacks a subject)
To fix a sentence fragment after a semicolon, you can:
* Add a subject and/or verb to make it a complete clause.
* Combine the fragment with the previous clause to create a single, complete sentence.
Remember: Semicolons are used to connect related thoughts, and those thoughts should be complete sentences.
