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.
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.
When appropriate, protection levels are automatically sensed, described and categorized.
