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.
To its plural form: This is a redirect from a singular noun to its plural form.
Redirects of this sort exist for reader convenience in cases of singular–plural pairs. It is also used for "false singulars", wherein the plural or plural-looking form is better attested in usage, such that the normal "prefer the singular" Wikipedia naming convention is not followed. Examples:
Use this rcat to tag qualified mainspace redirects only; if qualified singular forms are found in other namespaces, use {{R from modification}}instead.
