• Structure: 禁句 is read as きんく and is a noun for a word or subject that must not be mentioned within a particular relationship, group, or setting.
• Basic usage: Use 禁句になっている for an established taboo and 禁句として扱う for treating something as taboo.

2. Common pitfalls and similar expressions

• State and treatment
  • になる describes the resulting taboo status, while として扱う describes classifying and treating something as taboo.
