What is SkELL?

SkELL (Sketch Engine for Language Learning) is a simple tool for students and teachers of English to easily check whether or how a particular phrase or a word is used by real speakers of English.

No registration or payment required. Just type a word and click a button.

All examples, collocations and synonyms were identified automatically by ingenious algorithms and state-of-the-art software analysing large multi-billion samples of text. No manual work was involved.

SkELL vs. Google Search

SkELL finds good examples of the word or phrase useful for language learners.

Google Search finds web pages with information about the topic specified by the word or phrase.

Examples in context – concordance

skell_searchUse the Examples button to display examples of the word or phrase in context. Type a word (e.g. controllable) or a phrase (e.g. in regard to) and click the Search button, you will get up to 40 example sentences.

How it works

  • Base form will find its derived forms too, e.g. searching for mouse will mice. However, searching for mice (plural, not a base form) will only find examples of mice (not mouse).
  • Finds all parts of speech.
    If you search for book, it will get sentences with book as a verb as well as a noun and both in various word forms (booking, booked, books).

More complex searches and other languages

To find examples in other languages, to use more complex criteria or to search for grammar structures rather than concrete words, use the concordance search in Sketch Engine.

Technology behind SkELL

SkELL is a free simplified interface of Sketch Engine adapted to the needs of learners of English. Sketch Engine is a corpus query and management system holding 400+ corpora in 90+ languages. Sketch Engine is used by linguists, lexicographers, lexicologists and other researchers to learn about how language works. Sketch Engine currently handles about 150 TB (terabytes) of data at an unprecedented speed. It is also designed to handle morphologically rich languages such as Russian, Spanish or Japanese.

Data sources

All results in SkELL are a product of ingenious algorithms analysing fully automatically large multi-billion word samples of text, called text corpora. There is no manual work involved when generating the collocations, examples or thesaurus results. See more about the English corpus behind the English SkELL.

The text corpora contain a varied collection of texts such as news, academic papers, Wikipedia articles, open-source books, web pages, discussion forums, blogs, etc. to provide a good example of how language is used in everyday, standard, formal and professional context.
