This is our top-level category. (Looking at it another way, it is our root category!)
Ideally, every other category should be a subcategory of at least one other, and every article should be in at least one category; many will fit well into two (eg location and subject-matter). A full list of existing categories can be found at Special:Categories.
To add a new category, just add [[category:categoryname]] to the article or existing category page (after checking whether any existing category is suitable).
If two categories have overlapping subject-matter with each having some that's not in the other (eg Category:Indo-European and Category:Indian languages or Category:Europe and Category:Russia), they can each include (in the text portion) a link to the other, but neither should be a subcategory of the other. We will use the Categorisation page for detailed reasons and recommendations, including ways of arranging articles and subcategories in other than strict alphabetical order.
This category has the following 9 subcategories, out of 9 total.
