Wikipedia:Spellchecking
 | This page documents an English Wikipediaediting guideline. Editors should generally follow it, thoughexceptionsmay apply. Substantive edits to this page should reflectconsensus.When in doubt, discuss first on thetalk page. |
Spellchecking software can be helpful when copyediting Wikipedia articles. This page explains how to use it well and avoid conflicts with other editors.
General advice:
- Be sure to use the spelling for the correct dialect of a language (e.g., American English vs. British English).
- No spellchecker is completely accurate.
- Be extremely careful when editing pages written in languages in which you are not fluent.
- Grammar-checking tools can introduce more errors than they appear to fix.
- You are responsible for all spelling or grammar changes you make, even if the corrections were suggested by an error-checking tool.
Be careful with dialect differences[edit]
Be careful about setting the language of the software to the correct variety of English. If the article's topic is not linked to a particular region, use the same variety as the first non-stub version of the article. Check the talk page before editing variety-specific spelling; many articles have a template such as{{Use Hiberno-English}}near the top of its talk page that indicates the spelling to be used.
Use the article's variant consistently throughout the article (except in direct quotations), and use terms that are common to all varieties of English (e.g.,fixed-wing aircraftrather thanairplaneoraeroplane) whenever possible.
SeeWikipedia:Manual of Style § National varieties of Englishfor detailed advice, andWikipedia:Manual of Style/Spellingfor a table of spelling variants in different dialects.
Checking a single article[edit]
Using a web browser[edit]
The easiest way to spellcheck a single article is to use the built-in spellcheck of your web browser.
 | Regardless of the method used, care should be taken to make sure that your spellchecker does not break wikitext, as most of these spellcheckers have not been designed for wikis like Wikipedia. |
- Mozilla Firefoxhas a built-in spellchecking engine. However, you should check that the right dictionary for your language is installed and selected. Right-click in an editing field, make sure that "Check spelling" is checked, then under "Languages" select the right language. There are separate dictionaries for "English / United States", "English / United Kingdom" etc.; if the right dictionary does not appear in the list, click "Add Dictionaries" and use the page that appears to install it (note that you will have to restart Firefox to enable it after installing).
- Google Chromeprovides built-in spellchecking for each text field.[1]
- Microsoft Edgealso has a built-in spellchecker.
- Safarialso provides spellchecking features on Mac.
- Operahas a spellchecker.[2]
Browser extensions[edit]
- Grammarlyis a free plugin for popular web browsers that checks not only spelling, but also grammar, usage and punctuation.
- LanguageToolis an open-source tool that checks grammar and spelling.
Using an external website[edit]
- SpellChecker.orgis a free online spellchecker that requires no extension or add-on installation.
- WebSpellCheckeris a multi-language spellchecking engine that can be integrated into a website or aweb application.
Using word-processor software[edit]
Many office suites, such asMicrosoft OfficeandLibreOffice,are equipped with spell and grammar checkers that are on by default. Open the Wikipedia article, select "edit" from the menu atop the page or section, select and copy the article source, paste it into aWordorWriterdocument, follow the red (spelling) and green (grammar) markers, and correct mistakes as necessary.
To enable spellchecking in Microsoft Word, go to the Tools menu and enable "Grammar and spellchecking". When satisfied, copy and paste the text into the text box in the browser window, check that any UTF-8 characters are still working as before by clicking "Show changes", and, if satisfied, click "Publish changes", as usual.
In LibreOffice Writer, go to the top menu, select "Tools" → "AutoCorrect", and select "while typing" to enable checking.
Checking recent edits in bulk[edit]
If you have installed theanti-vandal toolinyour common.js,you can use thelive spellcheckto identify misspellings as they happen (recent edits). This is not a comprehensive spellcheck — it points out only the most commonly misspelt words. And it will not spellcheck text that an editor is adding to an article (for that, see the web browsers section, above).
Checking existing text in bulk[edit]
Spellcheck dictionary additions for editors[edit]
Wikipedia:Spellcheck dictionaryis an editor-compiled list of English words, terms, abbreviations and acronyms commonly encountered on Wikipedia. You may copy it and add it to your software's spell-check dictionary.
