- From an abbreviation: This is a redirect from an abbreviation to a related topic, such as the expansion of the abbreviation. Use this template for any length reduction other than the following.
- Instead of this template:
- use {{R from acronym}} for abbreviations that are pronounced as words, such as NATO and RADAR;
- use {{R from initialism}} for those abbreviations that are pronounced as letters, such as CIA and HIV;
- use {{R from short name}} for the initials of a person's name or for any other length reduction that is not typically classed as an abbreviation.
- From the plural form: This is a redirect from a plural noun to its singular form.
- This redirect link is used for convenience; it is often preferable to add the plural directly after the link (for example,
[[link]]s). However, do not replace these redirected links with a simpler link unless the page is updated for another reason (see WP:NOTBROKEN).
- Use this rcat to tag only mainspace redirects; when plural forms are found in other namespaces, use {{R from modification}} instead.
