I've only know the particle, wo to have only one use, which is to show when you're doing something, usually use before a verb.
Ex : sushi wo/o tabemasu
So what about
Ex : ringo wo futatsu kudasai
Futatsu is a number, not a verb...? I'm so confused.
kudasai before conjugation is kudasaru which means to give right, so it is a verb? That's why we got to use wo in this situation, doesn't matter whether if it is before a verb or after a verb?
I've only started a few weeks ago, I've got myself a Genki I and II, and mostly I learn it from a website called learnjapaneseadventure. I got it now thanks!
