Understanding ～時間目
The suffix ～時間目 (～じかんめ) is commonly used in Japanese schools to indicate the ordinal number of a class period or hour in a school day. For example, 三時間目 means "the third period" or "the third hour." It is a fixed expression used to organize the school timetable.
Usage and Context
This term is mostly used in educational settings, especially in schools, to specify when a class or activity takes place during the day. It can refer to any hour or period, from the first (一時間目) to the last, depending on the school's schedule.
Common Collocations
- 一時間目 (いちじかんめ): first period
- 二時間目 (にじかんめ): second period
- 三時間目 (さんじかんめ): third period
- ～時間目に (～じかんめに): at the ~th period (used to indicate when something happens)
Register and Politeness
This expression is neutral and commonly used in everyday school conversations, announcements, and schedules. It is neither formal nor informal but is specific to the context of school time management.
Learner Tips
A common confusion is mixing ～時間目 with just the number of hours (時間). Remember that ～時間目 specifically marks the ordinal position of a class period, not the duration of time. For example, 三時間目 means "third period," not "three hours."
Use ～時間目 when talking about school schedules or class timings to sound natural and clear.
