1.
homework, assignment
Work assigned by a teacher to be done outside of class. A fundamental part of Japanese education.
2.
unfinished task, pending issue
Can also refer to something left undone that needs to be addressed, like 'homework' from a meeting or project.
This issue is something we need to address. Let's come up with an answer by next week.
宿題 means homework assigned by teachers, but also extends to mean any unfinished task or pending issue.
ETYMOLOGY:
宿 (lodging/home) + 題 (topic/problem) = work to do at home
COMMON EXPRESSIONS:
- 宿題をする: to do homework
- 宿題を出す: to assign homework
- 宿題を忘れる: to forget homework
- 夏休みの宿題: summer vacation homework
FIGURATIVE USE:
In business contexts, 宿題 often refers to action items or tasks to complete before the next meeting: それは次回までの宿題です (That's homework for next time).
CULTURAL NOTE:
Japanese schools assign homework during all vacation periods, including summer. 宿題が終わらない (homework isn't finished) is a common student complaint.
