๐ Explanation
The expression ใใใใฉใใใ is used to create an indirect question that doesn't use a specific question word (like who, what, or where). It translates to "whether or not".
It is formed by taking the plain form of a verb or adjective, followed by ใใฉใใ. For Nouns and Na-adjectives, do not use 'da' before 'ka'.
This is commonly followed by verbs of knowing, asking, or checking, such as wakaru (to know/understand), shiru (to know), or kiku (to ask).
Iku ka dou ka wakarimasen.
= 'I don't know whether I will go or not.'
Hontou ka dou ka kikimashita.
= 'I asked whether it was true or not.'
