Please correct this for me?

I had studied English grammar for many years, but I couldn't speak.

Hi Gudtms,

There is no need to use the past perfect 'I had studied' because you would need to add another time/tense in the sentence as in: I had studied English before I went to college.

Your sentence could read:

I studied English grammar for many years, but I couldn't speak the language.
