mo ichidô
 

Can one combine "mo ichidô, omega shimasu" and "kurikaeshite, kudasai" into "mo ichidô, kurikaeshite kudasai"?

Do you want to say "please say it (again) one more time"?

In Japanese, "MOU ICHIDO,ONEGAI SHIMASU" would be natural.

"Please repeat one more time" is what I meant. I'm a martial arts teacher, and I would use it to let the student repeat the technique one more time.

You can use "MOU ICHIDO, ONEGAI SHIMASU" as well though it sound too polite for martial arts teacher. "MOU IKKAI!" would be more simple.

You seem to stick to the word "repeat". I omit it because Japanese word "MOU" involves repeating.

Okay, thanks!

And we're not that kind of Dôjô or martial art. We're very nice, kind and respectful to each other. No yelling or hard commands.
