十分

1. Origins, structure, and basic meaning

• Structure: In this entry, 十分 is read as じゅっぷん; it combines 十 with the time unit 分 to mean a duration of ten minutes.
• Basic usage: Use 十分かかる for elapsed time and 休憩は十分だけ for a break limited to ten minutes.

2. Common pitfalls and similar expressions

• Reading and meaning
  • The same spelling read as じゅうぶん means “enough,” so the time context requires the reading じゅっぷん.
• Limit expressed by だけ
  • 十分だけ restricts the break to only ten minutes; it does not evaluate ten minutes as sufficient.
