From a different spelling: This is a redirect from a title with a different spelling of the target name. Pages that link to this redirect may be updated to link directly to the target page if that results in an improvement of the text. Do not "fix" such links if they are not broken. Also, these links should not be replaced with piped links.
There are many more specific templates. See subcategories of Category:Redirects from modifications for other options (capitals, abbreviations, diacritics, plurals, stylizations, transliteration, ligatures, different parts of speech, etc.)
