Difference Between べんきょう する and べんきょうを する?

Question

What is the difference between べんきょう する and べんきょうを する?

Answer 1

べんきょう する is the verb "to study".

べんきょうを する is a phrase that can only be used if preceded by words or adjectives that can be used in conjunction with べんきょう. Example: にほんごをべんきょうする. I'm studying Japanese (present tense). You cannot say "にほんごをべんきょうをする." That would have two direct object particles, which would make the meaning of the sentence muddled. You could say "にほんごのべんきょうをする". A literal translation would be "I'm doing Japanese studies". I hope this helps!
