Latvian numerals
Fragment of a discussion from User talk:Rua
Not as such, but it does seem rather excessive to have one category for each kind of form...
I think in general, from the viewpoint of the casual user, all those PoS categories are pretty useless -- nobody is going to find the word they want by looking through Category:en:Verbs, for instance. I suppose the point of PoS categories is internal bookkeeping, stats, etc. Personally, I use them to look for mistakes (in principle, the number of dative plural forms must be equal to the number of dative singular forms minus the number of pluralia tantum (+ the singularia tantum); if the numbers don't match, then something is wrong... Not very efficient, but then again, better than nothing).
