Wiktionary:Entry layout | metadata
This is material which is edited in a regular edit box, but does not appear in the entry when it is read. In some cases where it appears depends on your user preferences, especially the skin that you have chosen.
A Wiktionary category is a group of related entries which are listed on a category page. Sub-categories may also appear on that page. Categories and lists under various names may seem very similar, but the way they are built is very different; in most cases, but especially in open-ended lists, they complement each other.
To include an entry in a category, simply add a category tag to the entry thus:
The link will appear at the bottom of the page in some skins and at the top in others, regardless of where it is placed in the edit box. Category links are placed one per line at the end of the appropriate language section. Putting these tags in a consistent place makes them easier to find in a longer entry’s edit field. A category link appears red if its category page has not yet been described, but categorized entries will appear there. You should edit a new category page, usually to add a brief description of the category and adding one or more tags to place it in a higher-level category.
By convention, it is preferable to use the plural for most category names that are nouns. This will avoid having a category divided in two when some use the plural and some use the singular.
