Help talk:Categories

Are plural or singular names preferred for categories? My guess is plural given that most of them are, but I've seen some exceptions. --barto (talk) 13:28, 28 January 2017 (EST)


 * Plural when the object being categorised is plural, singular when there is only one such object. At least, that's the sort of plan. --prime mover (talk) 15:11, 28 January 2017 (EST)


 * One is encouraged to expose exceptions to this rule as such. &mdash; Lord_Farin (talk) 04:48, 29 January 2017 (EST)


 * There's Category:External Direct Product. --barto (talk) 04:56, 29 January 2017 (EST)


 * My thinking there may have been along the lines of: "this is a category about the concept of forming the external direct product of... etc." It will be fixed. --prime mover (talk) 05:03, 29 January 2017 (EST)


 * ... job done. --prime mover (talk) 05:20, 29 January 2017 (EST)

How large should categories be?

 * The trouble with writing rules for this stuff is that in cases where the rule would not work, there would be a lot of trouble bending the natural structure out of shape in order to make it fit something arbitrary. --prime mover (talk) 17:45, 25 August 2017 (EDT)
