Linking from PIE entries to their root derivation categories
From User talk:Rua
Don't you think it would be a good idea to create some sort of link from PIE entries (such as *mer-) to their respective root derivation categories (Category:Terms derived from the PIE root *mer-)? One way to do this would be simply to categorize the former into the latter.
I tried {{#categorytree:Terms derived from the PIE root *sed-|depth=0|class="derivedterms Latinx"}}
, but it does not let me expand the subcategories (the ► is grayed out). And on this thread no ► appears at all even for the top category, so I can't expand anything:
Category Terms derived from the PIE root *sed- not found
