列席

1. Origins, structure, and basic meaning

• Structure: 列席 is read as れっせき and is a verbal noun for being present at a formal or ceremonial occasion.
• Basic usage: It is used for attending a wedding as a relative or a commemorative ceremony as a representative.

2. Common pitfalls and similar expressions

• Event particle
  • The attended occasion is marked with に, as in 結婚式に列席する.
• Formal range
  • Both examples involve ceremonial events, so the word is narrower here than simply joining a casual gathering.
