What is the difference between grammar mistake and grammatical mistake?
“Grammar” is a noun, and “grammatical” is an adjective. When we put a noun before a noun the first will somewhat modify the later but in a little bit different manner. Talking about a “football field,” we talk about a “field for football.” In the same manner, talking about “grammar mistake,” we talk about “mistake for grammar.” This interpretation may make a little sense but the words like “grammar suggestions” may do more. Grammatical means “about grammar,” “having to do with grammar,” or “concerning grammar.” If you will talk about some mistakes you found on the sentence in terms of grammar, I’d rather you call them “grammatical mistakes.” However when people say “grammar mistakes,” others understand what they are talking about. It’s just like when we say “It’s me,” and not “It’s I.” This is not a big deal. But it will be if this question is for an examination. Is there any grammarian coming across this question? Please help elaborating it. I want to know more myself.
