From a modification: This is a redirect from a modification of the target's title or a closely related title. For example, the words may be rearranged.
In cases of modification from distinctly longer or shorter names, please use {{R from long name}} or {{R from short name}}, respectively. An abbreviation should be tagged with {{R from initialism}} or, if it can be spoken like a word such as NASA and RADAR, use {{R from acronym}}.
Use this rcat instead of {{R from other capitalisation}} and {{R from plural}} in namespaces other than mainspace for those types of modification. This may also apply to several other subcategories of modification; please check those templates' output before saving if using outside of mainspace.
From an ambiguous term: This is a redirect from an ambiguous page name to a page or list that disambiguates it. These redirects are pointed to by links that should always be disambiguated. Therefore, this template should never appear on a page that has "(disambiguation)" in its title – in that case use {{R to disambiguation page}}instead.
