What is a sentence checker?
A sentence checker is a tool that tells you whether a sentence is correct and complete. It looks for run-ons, fragments, subjects and verbs that don't agree, and unclear structure. This one returns a corrected version of your text and lists each problem with the fix and a short explanation.
What makes a sentence complete?
A complete sentence has a subject, a verb and a full thought: "The store closes at six." "Because the store closes at six" is a fragment, since it leaves the thought hanging. Two full sentences joined by only a comma make a run-on. Use a full stop or a joining word instead.
