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.
From an alternative language: This is a redirect from a page name in Latin to a page name in Latin. These words may directly translate or they may be related words, names or phrases.
This redirect leads to its target in accordance with the naming conventions for titles in other languages and can help writing and searches. However, per WP:NOTBROKEN do not replace these redirected links with a piped link unless the page is updated for another reason.
From a printworthy page title: This is a redirect from a title that would be helpful in a printed or CD/DVD version of Wikipedia. See Wikipedia:Printability and Version 1.0 Editorial Team for more information.
