spelling checker

spelling checker (spell checker) A program, often a component of a word processing system, that will check any or all of the words in a document against a set of dictionaries; this set consists of a base dictionary and optional extra dictionaries specific to the subject of the document or created by the user. On finding a word not known to it the spelling checker may suggest alternative spellings and ask if the word is to be added to the dictionary. Spelling checkers cannot of course detect errors that are themselves valid words, while their attempts to find alternatives to proper names can be distinctly amusing.

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
