Foo lemma/Definition

This article contains just a definition and optionally other subpages (such as a list of related articles), but no metadata. Create the metadata page if you want to expand this into a full article.

Foo lemma [r]: This example of a lemma has only a definition page and an article page with the subpages template. The article transcludes the text from the definition page. The link to the article, when using the R template is shown in black to indicate it has no more content that the definition which can already be seen.
