Ways to say it
| Japanese | Romanization (Wiktionary) |
|---|---|
| 私は行かなければなりません | watashi wa ikanakereba narimasen |
| 私は行かなくてはいけません | watashi wa ikanakutewa ikemasen |
Use 私は行かなければなりません to express an obligation or necessity, often implying that circumstances or duty require you to go. The subject watashi wa, meaning I, is often left out when it is clear who is leaving.
What does it mean word for word?
行かなければなりません is built from ikanai, the negative of the verb to go, the conditional ending kereba, meaning if and narimasen, meaning it will not do. Literally it says if I do not go, it will not do.
Which one should you use?
Both 私は行かなければなりません and 私は行かなくてはいけません mean must go. ikanakereba narimasen is slightly more formal and common in writing or polite speech, while ikanakutewa ikemasen is a bit more common in spoken conversation.
How does it change in a sentence?
In casual speech with friends, the long phrase is often shortened to 行かなきゃ (ikanakya) or ikanakucha.
How do you pronounce it?
It is pronounced watashi wa ikanakereba narimasen. The particle wa after watashi is written with は, the kana usually read ha.
When do people say it?
When you actually take your leave, Japanese speakers often use a set phrase instead of saying they must go. しつれいします is a polite way to excuse yourself from a formal gathering. おつかれさまでした, thank you for your hard work, is common when leaving work. じゃ、いってきます, well, I'm off, is said when leaving home and じゃ、またね is a friendly see you later.
Did you know?
- In very formal settings, like leaving a meeting or a superior's office, one uses しつれいします ('shitsurei shimasu'), which means 'I am going to commit a rudeness' by leaving.
- Japanese speakers often avoid saying 'I must go' directly to avoid sounding blunt, instead using vague phrases like そろそろ (sorosoro), which suggests that the time for leaving is approaching.
- When leaving a home, instead of saying 'I must go', people say いってきます (itte kimasu), which literally translates to 'I will go and come back'.
