じゃｐしｔ

    hey. what is the volitional for できる？
    is it できろう？　or しよう？　like what if i want to say that” im worried if i can do this or not. できるかできないかと心配した　

できるかどうか分からない

Is Japanese your first foreign language? Don't push yourself to construct sentences that you clearly can't. If your teacher is making you keep a diary in Japanese, tell them to fuck off.
Disregard the above if you're in Japan and you actually need to know how to say that to save your life or something.

Having said that...

できるか否か心配です
できるかどうかわかりません
できる自信がありません

are some ways to say it.

There are two types of verbs, volitional and non-volitional.

「できる」is a non-volitional verb(無意思動詞）.



それにしても、下品なスレタイだな…

japshit?
