This hidden category deliberately ignores the MOS:CIRCA guideline to use "c." in articles, the MOS:DASH guideline for year ranges, or both. The category should not be moved.

This category is not shown on its member pages unless the appropriate user preference (appearance → show hidden categories) is set.

Administrators: Please do not delete this category as empty! This category may be empty occasionally or even most of the time.

This category contains articles with Middle Dutch-language text. The primary purpose of these categories is to facilitate manual or automated checking of text in other languages.

This category should only be added with the {{ Lang}} family of templates, never explicitly.

For example {{ Lang| dum|text in Middle Dutch (ca. 1050-1350) language here}}, which wraps the text with <span lang="dum">. Also available is {{ Lang-dum|text in Middle Dutch (ca. 1050-1350) language here}} which displays as Middle Dutch: text in Middle Dutch (ca. 1050-1350) language here.
