Redirect to:

This page is a redirect. The following categories are used to track and monitor this redirect:

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:
  - ScissorScissorScissors
  - TrouserTrouserTrousers
- Use this template to tag qualified mainspace redirects only; if qualified singular forms are found in other namespaces, use template {{R from modification}} instead.

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