Why are these words ungrammatical

grammatical-number grammar syntactic-analysis

I can't find the reason why : riceful and antful are ungrammatical. Can someone help me? Thanks


Solution 1:

I think you've misunderstood what grammatical means. The words you've cited are simply not used by anyone I've ever heard or read.

If they had a meaning they could be put in a sentence.

Let's give one a meaning: antful means the amount of something that could fill an ant.

You've got thousands of antfuls of milk there.

I have used that word grammatically.

A word without context is not ungrammatical, it's just meaningless.
