expression, suru verb (special)
meet in person; have the pleasure of meeting
Formal, literary expression for meeting someone face-to-face, often with a nuance of honor or privilege. Rare in modern conversation; found in formal writing or speeches.
先日、先生に謦咳に接する機会を得た。
The other day I had the opportunity to meet the teacher in person.
謦咳 (けいがい) originally referred to coughing and clearing one's throat, and by extension came to mean a person's voice or presence. The phrase 謦咳に接する literally means 'to come into contact with someone's voice/presence,' i.e., to meet them in person. The exact historical derivation is uncertain, but the expression is a classical Chinese-derived idiom.
