Complete Sentence Checker

Writing a document is a long and labored process that requires you to go through many different things to get it right, and one of the most important, but one that people also, unfortunately, often ignore, is the sentence check. This editing stage is crucial to make sure that your sentences are grammatically correct and error-free.

Let’s admit that many of us skip proofreading not just because it takes a good deal of time and effort, but also as it requires a lot of skill and expertise in terms of knowing complex grammar rules. And that’s what the check this sentence tool is here for.

The toughest part of completing the sentence check is simply making sure that you go through all the requirements and make sure that all your punctuation, words, syntax, structure, and formatting is correct. Doing so takes a level of knowledge and commitment that people often don’t have, but now all you have to do is enlist the help of our English sentence corrector and you can get the top-notch grammar that you need easier than ever! Whenever you’re looking how to fix run on sentences, our complete sentence checker is here to provide you with the services you need to get it right! It takes no time, is easy to use, and highly reliable!

When you’re correcting a sentence, with or without our English sentence checker, you need to keep in mind the following things:

  • Subject-verb agreement: you must remember that subject and verb both have to be either singular or plural. If the subject is represented by a collective noun, the verb is singular; if the subjects are connected by AND, the verb is plural, etc.
  • Apply parallelism: if you start with infinitive then all phrases should be in the infinitive. For example:
    Judy hated dancing, running, and exercising in general. 
  • Clauses vs. phrases: try not to confuse these two. Clauses contain noun+verb and may be joined by conjunction. Rest – are phrases.
  • Lay and lie: the endless debate of whether to put “lie” or “lay”. To break it down, “lie” means “to recline” and cannot have an object, while “lay” means “to put down” and requires and object. Examples:

    Let me lie down here.

    He laid the guitar by his side.

Completing a thorough sentence check is the toughest part of the editing process, and thus, its the one that people, unfortunately, commonly overlook or ignore.

After all, it doesn’t matter how good your content and ideas are if you can’t present them in a way that’s clear, understandable, and convincing. However, it takes lots of time to pore over each sentence as well as skill and expertise to know all the rules, but a correct sentence checker is here to make it easier than ever! Simply paste your paper into the sentence correction checker, and you’ll get it back right away with the changes made.

Sentence Structure. Sentence Elements

While this sentence checker can tell you if your sentence has all of the correct elements and if they are in the right place, you still need to know what they are. The following will run through all of the different parts of the sentence:

  • Subject:

This is who or what the sentence is about and will be mention once within the sentence. It can be a person, an animal, a place, a thing or even an idea. For instance, “Dog” is the subject in: “The dog sat.”

  • Verb:

This is the action that the subject has taken within your sentence. So in “The dog sat” the verb is “sat.”

  • Object:

Similar to the subject but this is the person or thing that is acted upon by the verb. For instance “Mat” in “The dog sat on the mat.”

  • Prepositional Phrase:

A prepositional phrase can be a word such as for, in, at, after, until, etc. It will modify one of the words in the sentence. For example “in the kitchen” in the sentence “The dog sat on the mat in the kitchen.”

  • Independent Clause:

An independent clause is a complete thought that contains as a minimum a subject and a verb. As such it is a complete sentence in its own right and can stand alone.

  • Dependent Clause:

Also called a subordinate clause this combination of subject and verb fails to provide a complete thought in its own right. As such it cannot stand as a sentence on its own and will usually need to be connected to an independent clause.

What Are the Main Types of Simple Sentence?

There are four types of a simple sentence that you will use within your writing and speech. Our “is this a full sentence checker” will be able to show you if the sentence you have used is correct. The following are the main types of sentences that you could use:

  • Simple or Declarative Sentence: this is the most commonly used and basic sentence and is used to relay information to your audience. It will always start with a capital letter and will end with a period: “The dog sat on the mat.”
  • Command or Imperative Sentence: these are sentences that tell someone to do something such as “Please turn off the light when you leave the room.”
  • Question or Interrogative Sentence: these are sentences that ask your audience a question. These will always end with a question mark: “Doe your punctuation and grammar have to be perfect?”
  • Exclamatory Sentence: these are sentences that make a statement while seeking to express strong emotion. They will often end with an explanation point: “The dog was huge!”

What Makes a Sentence Complete?

Many will use a proper sentence checker to see if their sentences are complete rather than fragments. To be a complete sentence it must:

  • Start with a capital letter and end with either a period, exclamation point, or a question mark.
  • Express a complete thought.
  • Contain both a subject and a verb.

If it does not contain all of the above then our “is this a complete sentence checker” will highlight your sentence for correction. Missing any of these points will show your sentence as a fragment.

How Do You Detect Incomplete Sentences?

If you are going to check if your sentences are complete you should look at each sentence in turn and ask yourself the following questions:

  • Who or what is the subject of the sentence? If there is no subject such as in “Then slipped in the wet mud.” Then the subject is a fragment as it does not have a subject.
  • What are they doing? For example: “The big fat opera singer.” There is no verb within the sentence.
  • Can the sentence stand as a complete thought? For example: “Because they fell down the stairs.” This sentence may contain a subject and a verb but the thought is incomplete and would be considered a subordinate clause or a fragment.

What Can Our Complex Sentence Checker Find in Your Writing?

Our professional free check writing software is able to fully check for all forms of structural errors in your sentences. It can successfully spot and help you to correct issues such as:

  • Run on sentences: our compound sentence checker will be able to see if there are two independent clauses that have not been separated by appropriate punctuation.
  • Sentence fragments: our online sentence structure help will be able to quickly show you any incomplete sentences within your writing.
  • Comma splice detection: similar to run on sentences a comma splice is where you separate the two clauses with only a comma and no coordinating conjunction. Our punctuation in compound/complex sentences checker will highlight and correct these issues.
  • Agreement between verb and subject: a common issue is having one singular and the other plural. Our subject-verb agreement checker will quickly highlight where you have made this common mistake.
  • No comma after an introductory phrase or word: another common error that our highly efficient software will be able to easily spot in your writing.

Manual Correction vs Online Sentence Detector: Which One Is Better?

Today’s digital migration has revived the craft of writing, albeit at a cost. On one hand, English language purists argue that overengineered editing software discourages creativity, while on the other hand, liberal scribes opine that they’re a much-needed time-saver. Depending on how you look at it, these two opposing opinions are correct in their respective capacities, although they do also have their downsides.

One thing we can all agree on, however, is that editing and proofreading can be a pain in certain anatomy parts that we won’t mention here. This is especially the case if you are line editing, which entails combing through your texts, line by line, identifying any underlying issues.

This brings us to the question: should you hire a human editor, use AI-powered sentence checkers, or both? Or even avoid editing altogether?

In this article, we are going to pit the two editing methods against each other to determine which one suits you best. 

Manual Editing

As indicated above, manual editing entails combing through your texts, line by line, and identifying and correcting errors. Let’s take a look at some of the benefits that a human touch brings to the editing and proofreading matrix.

Pros of Manual Correction

  • Contextual perspective. One of the biggest benefits of manual editing is the element of comprehension that a human editor brings. Although automated complete sentence checker free tools are getting intelligent courtesy of machine learning, they do fail to identify some obvious English grammar mistakes and errors. Human editors, on the other hand, can read, comprehend, and even pinpoint deep language errors, as well as make substantive suggestions. 
  • Substantive feedback. Another benefit of manual correction is that it allows you to do what online grammar checkers fail to—i.e, edit your texts wholesomely, as opposed to identifying and fixing proscribed errors in individual sentences. As such, when you switch pronouns accidentally, a professional human editor will catch that and suggest ways to avoid the mistake in the future.
  • Flexible. Unlike an overly restrictive and rule-based sentence construction checker, a human editor can easily adapt and assimilate to your preferences. For instance, you can request them to adopt a particular style or even look out for specific types of errors that you are prone to making.


  • Costly than an AI-powered sentence tester. Perhaps, one of the biggest downsides of manual editing is the cost attached to it. Unless you are self-editing, hiring a professional can be expensive, with costs running into the thousands of dollars. 
  • Time-intensive. Another major demerit of manual correction is its time-consuming aspect. Manually crawling through long manuscripts can take several weeks or even months, making it ideal for projects without a strict deadline. 
  • Monotonous. Professional editors deal with multiple projects daily. With time, the same old, boring routine can create boredom, causing them to overlook or miss errors.

Online Sentence Detector

An online grammar and sentence structure corrector is a computer program that crawls through your text identifying, grammar, spelling, punctuation, or any other grammar-related errors. And just like manual correction, sentence completers do have their advantages, as well as a fair share of criticism.

Pros of Using Online Parts of a Sentence Calculator

  • Saves time. Is your paper or publication due two hours from now? A quick parts of sentence checker is your best bet. These online tools let you easily pinpoint and correct a myriad of grammar mistakes in real-time. All you need is an Internet-enabled device and Internet connectivity, and you are ready to crack the whip. 
  • Versatile. As a student, you know all too well that professors place a premium on high-quality writing. As such, the last thing you want is to score low grades because you wrote a detailed, thoroughly researched paper about Paris when you meant Parish. And the same applies to all the other writing vocations and genres. With a single click of the mouse, an online incomplete sentence checker free tool can identify multiple concurrent mistakes, suggest the appropriate remedy, and even implement the changes. 
  • Free (sometimes). Unlike the ridiculously expensive process of hiring a professional editor, some grammar checkers do come with free-to-use software versions. With these free versions, you can conduct basic English grammar, spelling, and punctuation. Our parts of sentence checker go further to offer a free plagiarism checker. Using this feature, you can catch accidental plagiarism before clicking the submit or publish button. 
  • Customizable. Even with their limited features and functionalities, some free incomplete sentence checkers do offer some level of customizability. Depending on the tool you are using, you can select your preferred language, adjust the tone of your writing, disable it on certain websites, and even create a personal dictionary.
  • Easy-to-digest feedback. Along with identifying errors, a good incomplete sentence checker free tool provides detailed explanations and feedback for every mistake. In essence, you not only reap the benefit of polishing your work in real-time but also learn how to avoid the same mistakes in the future.
  • Available 24/7. Unlike a human editor who needs to take intermittent breaks to re-energize, online parts of sentence checkers are always available at a moment’s notice. What’s more, most of them are cloud-hosted, letting you edit your typed texts even when on the move. 


  • Does not always catch all the mistakes.
  • The free versions can be limited in terms of features and functionality depending on the software provider.
  • You need internet connectivity to use the online grammar checkers.

So Which One is Better? Manual Correction Vs Online Sentence Detector

As you can see, both human editors and AI grammar checkers have their merits and demerits. While AI has continued to greatly improve in terms of offering more tailored writing assistance, you should consider employing both tools. On one hand, the AI sentence checker will help identify the technical but equally sneaky grammar errors, while on the other hand, a human editor put the finishing touches.

You can always count on automatic sentence checker to get the job done?
