In many contexts, when you have no clue around something, the finest expression (and safest) you have the right to use 知らない (shiranai).

知らない (shiranai) is the negative kind of the verb 知る (shiru), which method “to know” in Japanese. Interestingly, the kanji, 知, which is supplied in both verbs method “wisdom” or “knowledge” in Japanese.

Therefore as soon as you speak 知らない (shiranai) in Japanese, you’re saying the you don’t have the wisdom or knowledge about something. 知らない (shiranai) is a an extremely general means to to speak “I don’t know” in Japanese, and you can also use the in regards to people.

A rapid thing around “I” and also “you” in Japanese… pronoun in Japanese are an extremely frequently omitted as soon as the context is clear. For this reason you’ll watch them lacking in the Japanese translations too.

I Don’t recognize in Polite Japanese

As Japanese is a polite language that provides honorifics (keigo), you might need to conjugate 知らない (shiranai) to the polite kind depending on the situation.

The polite type is a layout of speech that is scheduled for cases when you have to speak respectfully. These include, however are not restricted to, conversations v your manager, teacher or strangers.

In the polite form, 知らない (shiranai) i do not care 知りません (shirimasen). You can use the the same means as you would usage 知らない (shiranai) when you desire to to express a absence of knowledge on a topic.

今日は給料日ですか?知りませんでした!kyou ha kyuuryouhi desu ka? shirimasen deshita!Today is payday? i didn’t know!

In this example, you’re telling the human that you had no info on the reality that it’s payday.

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 second of the two most usual expressions to say “I don’t know” in Japanese. Rather than just “I don’t know”, once you use 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 pundit or emotional matters. When you say わからない (wakaranai) you’re saying that you do the efforts to recognize something, however were unable to so you 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 have the right to say:

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

In both of this examples, the speaker is saying they don’t recognize something, yet in the paper definition of not being able to understand. Due to the fact that they don’t understand, despite their efforts they just don’t know.

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

During instances when you’ve tried come understand and establish a deeper link to a person’s feelings, yet are unable to, you can use わからない (wakaranai). Alternatively, if friend do know you have the right to use わかる (wakaru), the course.

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

Difference 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 知らない (shiranai).

知らない (shiranai) is purely informational. When you have not heard/seen or read around a certain topic, you deserve to use 知らない (shiranai). It’s indicative the a lack of superficial information about something. Therefore, when you to speak 知らない (shiranai), you’re saying that you carry out not possess details or understanding on a topic.

Whereas わからない (wakaranai) reflects that you tried to know something yet were unable to. Making use of わからない (wakaranai) invokes a deeper definition and has a nuance that you tried to relate and also connect to the other person. 

There is an exception to these rules, and I think it’s worth stating so you don’t accidentally say the wrong point to someone.

If someone were to ask you, “hey is the bus stop roughly here?” for instance… based on the explanations I mutual above, you can think come say 知らない (shiranai). This is not have to wrong, it’s grammatically exactly actually. Yet I think native Japanese speakers would choose using わからない (wakaranai), or rather, the polite わかりません (wakarimasen) if speaking v a stranger. 

This is since わからない (wakaranai) conveys a lot softer “no, i don’t know” rather 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, although the speaker is questioning for info from you, saying 知らない (shiranai) comes throughout as a blunt “No, ns don’t know, why would certainly I?” type of answer.

Instead, using わからない (wakaranai) acts as a much gentler negation that conveys something follow me the currently of “I’m not as well sure, I’m not very acquainted through this area” type of thing.

This is similar to exactly how the Japanese protect against saying “no” straight to things. It’s in the society to be polite around your response to conserve the other persons face.
