Tired of grappling with those never-ending sentences that wreck your writing flow and leave your readers confused? We get it. Sentence Checkup’s sentence checker will help you make complex sentences clearer and easy to read.
What is a Run on Sentence?
A run on sentence combines two or more independent clauses in one sentence without proper punctuation or conjunctions. It thus results in sentences that are too long and often confusing and hard to read. Think of them as sentences that are cramming multiple thoughts or ideas together without giving the reader a clear break.
How can sentence checker help?
The Sentence Checkup’s sentence checker is like having a skilled editor by your side. Our sentence checker improves your writing by making those cumbersome sentences more accurate, clear, and readable.
Simply copy and paste the text, and the tool will identify and correct run on sentences, fargments and structure issues.
Refine and Fix Your Sentence
Corrects Comma Splices
The checker identifies and fixes comma splices. Change “He loves cooking, he often experiments with new recipes” to the grammatically correct “He loves cooking; he often experiments with new recipes.” No more pesky comma splices!
Detects and Corrects Punctuation
The punctuation checker suggests where to add necessary punctuation marks like commas, semicolons, or periods.
Adds Conjunctions
It may recommend adding conjunctions (like ‘and’, ‘but’, ‘although’, etc) to connect clauses properly. For example, in “I was tired I still finished the project,” the tool might suggest “I was tired, but I still finished the project.”
Splitting Sentences
The tool suggests splitting a run on sentence into two or more separate sentences. From “She enjoys painting her artwork is quite impressive,” it would make two sentences: “She enjoys painting. Her artwork is quite impressive.”
