FAQs

How do you check if a sentence is a run-on?

A run-on sentence improperly combines two or more independent clauses without correct punctuation or conjunctions. For example, 'John went to the store he bought some apples' is a run-on. The correct version adds a conjunction or proper punctuation, like 'John went to the store, and he bought some apples.'
What are the 3 types of run-on sentences?

The major types include fused sentences (clauses joined without any punctuation), comma splices (independent clauses joined using only a comma), and polysyndeton (sentences with excessive or unnecessary conjunctions).
How can I check for fragment sentences online for free?

You can use free online sentence checker tools, like SentenceCheckup, to identify and correct sentence fragments for enhanced clarity.
What are the 5 rules to fix a run-on sentence?

Common methods to correct a run-on sentence include using a period to create separate sentences, using a comma followed by an appropriate conjunction, adding a transitional word with proper punctuation, using a semicolon, or using a subordinating conjunction.
What is the difference between a fragment and a run-on sentence?

A sentence fragment is an incomplete thought lacking essential elements like a subject or verb. Conversely, a run-on sentence contains two or more complete thoughts (independent clauses) that are incorrectly joined without proper punctuation or conjunctions.
