塾講師

1. Origins, structure, and basic meaning

• Structure: 塾講師 (じゅくこうし) is a compound noun naming the occupational role of an instructor at a cram school.
• Basic usage: 塾講師として働く marks an occupational capacity with として, while 塾講師が質問を整理する makes that person the agent of the action.

2. Common pitfalls and similar expressions

• Institutional role in the examples
  • The first example explicitly marks the role with 塾講師として. The second also places the instructor with a student, so these examples do not support widening 塾講師 to any teacher unrelated to a cram school.
