π Sentence Fragment vs. Run-on Sentence: Spotting the Difference
Understanding sentence structure is key to clear and effective writing. Two common errors are sentence fragments and run-on sentences. Let's define each and then compare them side-by-side.
π― Definition of a Sentence Fragment
A sentence fragment is an incomplete sentence. It may lack a subject, a verb, or both. It does not express a complete thought and cannot stand alone.
βοΈ Definition of a Run-on Sentence
A run-on sentence occurs when two or more independent clauses (clauses that could stand alone as sentences) are improperly joined. This usually means they are joined without proper punctuation or a coordinating conjunction.
