Usage of ～番
The suffix ～番 is used to indicate order or number, similar to "-st", "-nd", "-rd", or "-th" in English. It is attached to a number to specify position, rank, or a numbered item.
Common contexts
- Ordering in a sequence (e.g., first, second, third)
- Numbering platforms, seats, or items
- Identifying a specific number in a list or group
Collocations and patterns
- ～番目 (～ばんめ): explicitly means "the nth"; often used to emphasize order.
- ～番線 (～ばんせん): platform number, commonly used in train stations.
- ～番席 (～ばんせき): seat number.
Notes
When using ～番, it is common to combine it with counters or nouns to specify what is being numbered. For example, 三番目 (third), 五番線 (platform five). Learners sometimes confuse ～番 with ～回 (times/occurrences), so remember ～番 is about order or position, not frequency.
The form is neutral and can be used in both formal and informal contexts.
