Generate random English sentences instantly — filter by category, tone, type, and length. One click, no sign-up.
Every word generator you need, all free
A random sentence generator creates complete, correctly formatted English sentences. These can be used as writing prompts, starting points for stories, examples of correct sentence structure for grammar exercises, or creative writing warm-ups. Each time you press generate, you will receive a fresh, randomly generated English sentence.
Need help overcoming writer's block? Writers often generate a list of 5 sentences in the category of their current project. They might choose a sentence from the list of Adventure sentences to start an action scene, a Mystery sentence for suspense, and so on. Often, a writer will use one of these as a first line or scene starter. Pairing this tool with the above random word generator helps writers who are stuck with fresh vocabulary for their creative writing.
The sentence type filter is a very useful feature for grammar study. The four main types of sentences are shown with real examples of each type instead of typical abstract grammar examples.
To study grammar, use the filter by sentence type. A simple sentence has only one independent clause. A compound sentence has two or more independent clauses joined by a coordinating conjunction (for, and, nor, but, or, yet, so) or a semicolon. A complex sentence is made of one independent clause and at least one dependent clause. A compound-complex sentence is made of two or more independent clauses and one or more dependent clauses. By reading the examples of each type of sentence, you will be able to see the differences between them more easily than with a diagram.
A random sentence generator allows you to study vocabulary within a context. This is particularly helpful for English learners, as it lets them read different types of sentences in a natural context. You can also filter by tone (such as neutral or formal) and by sentence length (short, medium, or long) to match your practice needs. For example, studying within the Food & Cooking category will allow you to read and learn a range of sentences expressing ideas related to Food & Cooking; within a Work & Career category, you will learn a range of expressions related to Work & Career.
Teachers can set up their own exercises of sentences of simple, compound, complex, or compound-complex structure and have students identify them, or even change them. The copy-all button allows for easy exporting of a batch of such sentences. By also choosing a tone (Humorous for instance for fun exercises in class) and a category (such as Work & Career for professional language) writers can be given prompts for writing pieces needed for lessons on specific topics. Word-count annotations can also be turned on to get an immediate view of the number of words in a given sentence, which will in turn indicate the level of complexity of the given sentence.
No matter what kind of project you are working on, there are many different emotional registers, or moods, that you can use to write. For example, a Nature sentence written in a Poetic tone will look very different from the same sentence written in a Dramatic tone. That's why we have included the tone filter in the random sentence generator. Using this in conjunction with the category filter, you can pick sentences that are specifically relevant to your project. These might be Friendship + Inspirational for a speech, for example, Mystery + Suspenseful for a book opening, and Science & Technology + Neutral for an explainer.
A random sentence makes a great improv prompt, a good start for collaborative storytelling or even a party game. Use a long, dramatic sentence to start for your players, and challenge them to continue the story within a minute. If you're playing for fun, use Humorous sentences, and if you're trying to have a tense time playing, use a Suspenseful sentence. Use the spacebar to cycle through the results without using your mouse and get back to having fun.
A simple sentence is one independent clause, or subject-verb, such as I hike at Marten Peak every June or I use endearments to signal familiarity. The Sentence Type filter produces a bunch of examples for each of these to look at. A compound sentence is two independent clauses joined by a coordinating conjunction such as and, but, or, nor, or by a semicolon. Each independent clause could stand alone as a separate sentence. A complex sentence contains one independent clause and one or more dependent clauses. The dependent clause cannot stand alone as a complete sentence. It begins with a subordinating word such as because, although, even though, when, after, until, while, or before. A compound-complex sentence is a combination of two or more independent clauses and one or more dependent clauses. The dependent clauses cannot stand alone as complete sentences.
You can use all generated sentences as models and examples, but for academic writing, write your own. Use them as prompts, examples, and creative material. Yes, all generated sentences are provided as examples and are free to use without restriction. For academic writing, use these generated sentences as models to study, not to copy or adapt. Study them. Write your own sentences instead.
The Category filter narrows the results to a certain area of content. So, for instance, selecting "Nature" would only bring you results with the topic of nature in them. The same is true for the Tone filter, which controls the degree of "Neutral" or "Emotional" (i.e., "Dramatic" or "Poetic," etc.) that is found in the generated text. You can use this with the Category filter to get highly targeted results (for example, "Mystery" + "Suspenseful" would find a set of suitable sentences to open a thriller).
Narrow filters (like a specific category, rare tone, and specific sentence type) can result in a very small pool of matching sentences. Because we never attempt to recreate the same sentence in order to fill out the requested quantity, there can sometimes be fewer sentences actually generated than you request. We recommend that you make one of your filters broader, for instance, changing the Length filter from "Longer" to "Any" and/or the Tone filter from "Any" to "All".
