反映

1. Origins, structure, and basic meaning

• Structure: 反映 (はんえい) is an action noun for incorporating opinions or feedback into a plan or design.
• Basic usage: 意見を計画に反映した actively incorporates residents’ views into a plan, while 声が設計に反映されている passively describes user feedback embodied in a design.

2. Common pitfalls and similar expressions

• Active object and passive subject
  • In 意見を反映する, the views are an object; in 声が反映される, the same kind of content is the passive subject. 計画に and 設計に mark where the result is incorporated.
