What is the difference, if any, between "ungrammatical" and "infelicitous" as linguistic terms?
I haven't had much luck finding an answer to this question on the 'net. We all know that a phrase or sentences is ungrammatical if it violates the morpho-syntactic rules of a given language. So "I play ball," is grammatical but "*Me play ball," is ungrammatical in General Western English.
I'm betting that "*Me play ball," could also be called "infelicitous" in General Western English.
So, in linguistic terminology, are the terms "infelicitous" and "ungrammatical" synonymous? Or is the term "infelicitous" a more general term, encompassing the violation of more than just morpho-syntactic rules?
