Why limit to a tree? We don't want cycles, but I can certainly see the use of having a category be a subcategory of more than one parent. For example, Computing should fall under both Mathematics and Engineering.
Is there any specific reason for insisting on tree (as opposed to DAG) structure? — This unsigned comment was added by Dmh (talk • contribs) at 8 September 2005.
I noticed that for the definition of juggernaut, there is a reference to a British English entry.
Shouldn't there be a way to designate the difference between British English and American English if the word or phrase is primarily attributed to one or the other?
Should these be a categories such as Category: British English, Category: American English? or is there some other prescribed notation to use on a specific entry. Something akin to or . Searches on Wiktionary, Yahoo, and Google have turned up no help on this topic.
Wiktionary:Categorization#Categorizing words by language gives the following example of ideal entry categorization:
Is that right? From my understanding of our category "tree", the word "mare" should be categorized in Category:English nouns, Category:Latin nouns, Category:Italian nouns, and Category:Romanian nouns and Category:Romanian adjectives, each of which is a descendant category of the "language" categories above. I apologize if everyone already knows this, but I ask in order to correct the ideal example and to correct the similar recommendation at WT:AJ#Categories. Rodasmith 01:42, 4 May 2006 (UTC)
Should sets only have things that are in the set, or should they have related terms? (e.g. should Category:en:Horses contain neigh or only kinds of horse)--Simplificationalizer (talk) 00:09, 7 April 2017 (UTC)
Presently, the second paragraph reads, “…but it may be wise not to put a page in a category and also in a more general category”. I am changing this to “…entries should rarely—if ever—be put into a more narrow category and also a more general category”. I cannot think of any circumstance where something should be in both a parent and child category but if it should ever happen, it should be very rare and justified.

The Etymology sub-section of Main branches advises to list any etymology-related categories in {{etyl}}; however {{etyl}} has been deprecated and is due for deletion. {{der}}, {{bor}}, and {{inh}} have been created in their place; and the use of any of them depends on the manner of adoption from the source language. Can somebody please update the section to include this? BlueCaper (talk) 16:52, 26 June 2018 (UTC)
