It's a word, of course. The infinitive is もどる（戻る = to return）. もどろう is its volitional form.

勉強にもどろう, therefore, means "Let's get back to our studies."

Right. "~~ was saying" instead of "~~ said". 言ってた is the colloquial form of 言っていた.　"A syllable-saver" is the term I've been using on JF the last few weeks.

It's no bother. I'm here for that very purpose.

　

Oh, duh! I know that もどるmeans return, I just didn't get that もどろうwas the volitional form. It seems so obvious now, hahah I'm an idiot :D Thanks for the explaination.
You're so nice, thank you so much for your patience and time. I hope that maybe someday my Japanese will be good enough that can return the favor and help a Japanese person learning English the way you've helped me. ;)

By the way, your English is incredible :eek: English is probably a lot harder to learn than Japanese due to the many irregularities that the English language has comparitvely. Most of the spelling for English words is irregular and makes no sense, and our verbs are irregular too, not at all like the neat and logical Japanese system of verb conjugation. And your spelling and grammar is better than most of the native English speakers using this forum! How'd you get so good?
