Sentence Stack - a powerful Linguistic Search Engine backed by 300+ million sentence examples

Not certain precisely how to say it? That's ok. Just type in your phrase and see if you hit the mark. Our search provides exact matches, near matches, frequency comparison, and even sentence correction.

Sentence Explainer

Idiomatic phrases make learning English difficult, so we automatically detect idioms in your query and explain what they mean. Just paste in a sentence and see if there are any idioms hiding in it.

Free and Accessible

The best tools in the world are pointless if the people that need them most cannot afford them. That's why providing free tools is central to our mission. You won't find a competing service with a more generous offering.

Top English Sentences

The sentences in our search engine come from the best journals, encyclopedias, and news sources. In addition, we continue to manually refine the quality of our sentences so that you are always learning from the best examples.

Dictionary & Thesaurus

When you enter a single word into our search engine, the built-in dictionary and thesaurus will provide a definition and synonyms. And, we would not be a sentence search engine without also giving you example sentences containing the given word.

Grammar Check

Sometimes you just need to quickly check your sentence to ensure its grammar, spelling, and punctuation are correct. We've got you covered. Just paste it in and we will automatically scan it for errors.

Advanced Search

Our sentence matching technology combines Natural Language Processing, Information Retrieval, and Machine Learning (AI) to deliver relevant examples that help you express yourself accurately and with confidence.

Actively Developed

If you've been around here a while, you know that our service is under heavy development and always evolving to better meet your English language learning needs. Let us know what we can do to improve!

Contextual Learning

You cannot truly understand a word or phrase by definition alone. The meaning of words and phrases in natural language is embedded in the context of an entire sentence. And, you're in luck, we have 300+ million sentences.

I use Sentence Stack any time that I am uncertain how to use a word or phrase.

“ A great example of this was when I was writing this testimonial. I was not sure if it's correct to say 'any time' or 'anytime'. These moments of uncertainty happen a lot and I'm so thankful to have this service. ”

More than a Sentence Search Engine

A linguistic search engine (LSE) combines advanced sentence search with other capabilities like sentence correction, idiom detection, dictionary lookup, thesaurus, translation, and more. These broad features make it an ideal tool for all the facets of language learning including studying vocabulary in context, grasping word choice nuances, mastering language mechanics like grammar and spelling, and just having fun exploring English.
