Understanding Nakereba Narimasen
The phrase nakereba narimasen is used to express strong obligation or necessity—similar to “must” or “have to” in English. It is considered polite and formal, making it suitable for both spoken and written Japanese, especially in situations where you want to be clear and respectful.
Breaking Down the Structure
Let’s look at how nakereba narimasen is constructed:
- Verb in the nai-form: Start with the negative form of the verb (nai-form).
- Replace nai with nakereba: Change the “nai” ending to “nakereba”.
- Add narimasen: Attach “narimasen” (the negative form of “to become”).
Literally, it means “If [I] do not do [verb], it will not become (good/acceptable)”, which translates to “I must do [verb]”.
Step-by-Step Conjugation Example
Let’s use the verb taberu (to eat) as an example:
- Convert to nai-form: taberu → tabenai (not eat)
- Replace nai with nakereba: tabenai → tabenakereba
- Add narimasen: tabenakereba narimasen (must eat)
