Spelling suggestion is a feature of many computer software applications used to suggest plausible replacements for words that are likely to have been misspelled.

Spelling suggestion features are commonly included in Internet search engines, word processors, spell checkers, medical transcription, automatic query reformulation, and frequency-log statistics reporting.


Algorithms for spelling suggestion may incorporate several information resources to determine candidates for misspelled words and the words' likely correct replacements, including the following:

  • Frequency of a word's occurrence in reliable data sources
  • Search query logs
  • List of frequently misspelled words
  • Domain specific data resources (eg: corpora of medical terms)
