I Don’t know in Japanese

I Don’t Understand.わからない。wakaranai.わからない.mp3

わからない (wakaranai) is the 2nd of the two most typical expressions come say “I don’t know” in Japanese. Quite than just “I don’t know”, once you usage わからない (wakaranai), the an interpretation is closer come “I don’t understand.”

Consequently, わからない (wakaranai) is reserved for mostly intellectual or emotional matters. When you speak わからない (wakaranai) you’re saying the you do the efforts to know something, however were can not to so friend don’t know.

あなたが言ってることわからない。anata ga itteru koto wakaranai.I don’t recognize what you’re saying.

Or, you can say:

日本語がわからない。nihongo ga wakaranai.I don’t know/understand Japanese.

In both of these examples, the speaker is speak they don’t know something, yet in the context of no being able to understand. Since they don’t understand, despite their initiatives they just don’t know.

わからない (wakaranai), and the affirmative kind わかる (wakaru), meaning to “understand” in Japanese has actually a nuance that the trying to relate come the speaker and also their words/feelings.

During instances when you’ve tried come understand and also establish a deeper link to a person’s feelings, however are unable to, you deserve to use わからない (wakaranai). Alternatively, if girlfriend do recognize you can use わかる (wakaru), of course.

気持ちいわかる。kimochi wakaru.I understand/know exactly how you feel.

Difference in between わからない (wakaranai) & 知らない (shiranai)

Let’s summarise the differences between わからない (wakaranai) and also 知らない (shiranai).

知らない (shiranai) is completely informational. When you have not heard/seen or read around a particular topic, you can use 知らない (shiranai). It’s indicative that a lack of superficial information around something. Therefore, as soon as you to speak 知らない (shiranai), you’re saying the you perform not possess information or understanding on a topic.

Whereas わからない (wakaranai) shows that you tried to recognize something yet were can not to. Using わからない (wakaranai) invokes a deeper an interpretation and has actually a nuance that you tried come relate and also connect come the other person. 

There is an exception to this rules, and I think it’s worth discussing so friend don’t accidentally speak the wrong thing to someone.

If someone to be to questioning you, “hey is the bus stop about here?” because that instance… based on the explanations I common above, you might think to say 知らない (shiranai). This is not necessarily wrong, it’s grammatically exactly actually. Yet I think indigenous Japanese speaker would favor using わからない (wakaranai), or rather, the polite わかりません (wakarimasen) if speaking through a stranger. 

This is due to the fact that わからない (wakaranai) conveys a lot softer “no, i don’t know” quite than 知らない (shiranai). Just saying 知らない (shiranai) have the right to come across as somewhat cold. In this situation, return the speak is questioning for information from you, speak 知らない (shiranai) comes across as a dull “No, i don’t know, why would certainly I?” type of answer.

Instead, making use of わからない (wakaranai) acts together a lot gentler negation the conveys something along the present of “I’m not as well sure, I’m not very acquainted through this area” sort of thing.

This is comparable to how the Japanese stop saying “no” directly to things. It’s in the culture to be polite around your response to save the various other persons face.
