模型

1. Origins, structure, and basic meaning

• Structure: 模型 (もけい) is a reduced or simplified representation of a real object. It appears as a product and an explanatory tool.
• Basic usage: A child makes a wooden model ship; a model demonstrates a building interior.

2. Common pitfalls and similar expressions

• Replica constructed and model used to explain structure
  • 船の模型 links original and representation; 模型で示す marks means. It is not the actual ship or building.
