[Vocabulary] to make bad mistakes in grammar/spelling

[englishhobby]

Is the expression "to make bad mistakes in grammar/spelling" natural? Can "bad mistake" be associated with studies?

 

[emsr2d2]

If you use "bad mistake", what's a "good mistake"?

 

[englishhobby]

I don't know. I also thought about it when I saw in a textbook (not made by native speakers) the following: He speaks Spanish badly. He makes bad mistakes. If it's wrong, what is the best adjective to describe very"rude"grammar mistakes? His grammar is poor. He makes ..... rude? mistakes.

 

[tedmc]

If someone could make a slight mistake or a terrible mistake, I guess he or she could equally well make a bad mistake.
Of course there is no good mistake.

Not a teacher

 

[englishhobby]

Logically, yes, but we need native speakers to confirm or deny it.

 

[Rover_KE]

I confirm it.

 

[Roman55]

I am not a teacher.

Of course it's OK. Bad isn't always to be contrasted with good.

What about 'a bad accident' or 'a bad headache'? It's just a degree of severity, as it is in a bad mistake.

what is the best adjective to describe very"rude"grammar mistakes?

Can 'glaring' be used?

Not a teacher.

 

[emsr2d2]

We tend to use "glaring errors" rather than "glaring mistakes". I would use "serious mistake" rather than "big mistake" though. However, I take the point that "bad" does not always have to be contrasted with "good". I was being a little facetious.
