When used with the "Redirect category shell" (Rcat shell) template:
This page is a redirect. The following categories are used to track and monitor this redirect:
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 onlymainspace redirects; when plural forms are found in other namespaces, use {{R from modification}}instead.
When appropriate, protection levels are automatically sensed, described and categorized.
Template {{Redirect category shell}} may be used to add one or more rcat templates, along with their parameters and categories, to a redirect. For more information, see the documentation page below.
When used by itself:

Breaking changes to this template, such as moving it or nominating it for deletion, should be communicated to Twinkle's users and maintainers at Wikipedia talk:Twinkle as a courtesy. The standard installation of Twinkle relies on this template. Thank you.
Please do not alter the printworthy settings of this rcat without first notifying the Version 1.0 Editorial Team, who are responsible for any and all materials, including redirects, that go into a printed version of Wikipedia.
Add this rcat to a redirect page (not a talk-page redirect) in the following manner:
#REDIRECT[[(target article title)]]{{Rcat shell|{{R from plural}}{{R unprintworthy}}}}
Template {{Rcat shell}} is an alias for the Redirect category shell template, which may be used to add as many appropriate rcats as needed, usually from one to seven, along with their parameters, to a redirect. For more information see the documentation on its template page. This rcat may also tag a redirect individually:
#REDIRECT[[(target article title)]]{{R from plural}}
Use this rcat to tag any mainspace redirect from the plural noun of a singular target.
For redirects that target a related word or phrase, the |of= parameter can be used to clarify. For example, the Domestic cats redirect targets Cat and is tagged as follows:
{{R from plural|of=domestic cat}}
The text will then be altered to include, ...from a plural noun to its singular form or to a broader article; the singular form is "domestic cat".
Some plurals are printworthy, for example the Arabic and Latin forms. When you add this rcat to a redirect that you decide is printworthy, then use the unnamed parameter to subdue the unprintworthy category[clarification needed] in the following manner:
{{Rcat shell|{{R from plural|1=printworthy}}{{R printworthy}}}}
or the 1= may be omitted:
{{Rcat shell|{{R from plural|printworthy}}{{R printworthy}}}}
