How do you say "I still don't really understand" in Japanese?

Quick use

Use まだよくわかりません (mada yoku wakarimasen) when you still do not really understand something.

It is useful when the topic, explanation, or Japanese itself is not clear yet.

Chunk or pattern

• This is a fixed phrase.
• Learn the whole line first.
• You can use it before asking the person to explain again or more slowly.

Light form contrast

• わかります (wakarimasu): I understand.
• わかりません (wakarimasen): I do not understand.
• まだよくわかりません: I still do not really understand.

Practical note

This is softer than only saying わかりません. まだ and よく make it sound like you are still trying to follow.
