Is There Any Semantic Purpose to That?

The categories are count noun and mass noun correct and form noun. I have not heard of any language that has anything like form nouns as far as I'm looking at. The thing with them is that the singular collective paradigm, but we can also form a plural. Some of the distinctions are obvious. You know, abstract nouns are more likely to be form or mass. Solid objects are more likelyto be count unless they're really small, like a grain of sand. That's for one of the nouns systems I think there are actually three nouns systems in play.
