Formation
- The counter follows the particle and precedes the verb: 切手を二枚買いました
- Frequency: period + に + times: 一週間に二回
- Duration: time + かかる: 三十分かかります

Important notes
- A counter usually goes after the particle and before the verb: 切手を二枚買いました. The native series ひとつ … とお ends at ten; from eleven use a number with a counter: 十一個.
Common mistakes
- Choose the counter by the object: 人 for people, 枚 for flat things, 本 for long things. A point in time is not a duration: 三時に (at three) vs 三時間 (for three hours).
