A quick thing around “I” and “you” in Japanese… pronouns in Japanese are very frequently omitted when the context is clear. Thus you’ll check out them absent in the Japanese translations too.

The polite form is a layout of speech that is booked for situations when you must speak respectfully. These include, however are not minimal to, conversations v your manager, teacher or strangers.

In the polite form, 知らない (shiranai) becomes 知りません (shirimasen). You can use that the same method as girlfriend would usage 知らない (shiranai) when you want to refer a absence of expertise on a topic.

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 2 most common expressions come say “I don’t know” in Japanese. Fairly than just “I don’t know”, as soon as 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 emotionally matters. When you say わからない (wakaranai) you’re saying that you do the efforts to know something, yet were unable to so girlfriend 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 understand what you’re saying.

In both of these examples, the speak is speak they don’t recognize something, yet in the context of not being able to understand. Due to the fact that they don’t understand, despite their efforts they simply don’t know.

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

During instances when you’ve tried come understand and also establish a deeper connection to a person’s feelings, however are can not to, you deserve to use わからない (wakaranai). Alternatively, if friend do understand you deserve to use わかる (wakaru), of course.

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 completely informational. When you have not heard/seen or read around a particular topic, you deserve to use 知らない (shiranai). It’s indicative of a absence of superficial information around something. Therefore, as soon as you say 知らない (shiranai), you’re saying the you execute not possess info or expertise on a topic.

Whereas わからない (wakaranai) mirrors that you tried to know something but were can not to. Utilizing わからない (wakaranai) invokes a deeper an interpretation and has actually a nuance the you tried to relate and also connect come the various other person. 

There is an exception to these rules, and also I think it’s worth pointing out 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 common above, you might think come say 知らない (shiranai). This is not necessarily wrong, it’s grammatically correct actually. But I think indigenous Japanese speakers would like 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 because わからない (wakaranai) conveys a much softer “no, i don’t know” rather than 知らない (shiranai). Just saying 知らない (shiranai) can come across as rather cold. In this situation, back the speak is asking for details from you, saying 知らない (shiranai) comes throughout as a blunt “No, ns don’t know, why would I?” type of answer.

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

This is similar to exactly how the Japanese avoid saying “no” straight to things. It’s in the society to be polite about your solution to save the various other persons face.
