1. Origins, structure, and basic meaning

• Structure: 俗 relates to social customs or common popular usage; its on-reading is ぞく.
• Basic usage: 風俗(ふうぞく) can mean customs, 俗語(ぞくご) means slang, and 通俗(つうぞく) describes a popular or accessible character.

2. Common pitfalls and similar expressions

• Popular usage and evaluation
  • 通俗的な言葉 can be wording that makes difficult material accessible. The presence of 俗 does not always express criticism of vulgarity.
• Register of slang
  • 俗語 is associated with informal group or conversational usage. In official documents, a more general or formal expression may be preferable.
