Need some help with Japanese sufix? Okay so some time ago i had this test and I was supposed to translate "while reading" in a very polite way(i don't know how to translate it to English so that it's respectful enough). Anyways, there were 2 options and I only knew one, which was adding -itsutsu to yomu; but I don't know about the other one... -inagara wouln't be polite enough right? So maybe sufix -(r)are? But then it won't have the "while" meaning... Anyone help?
