noun
splendid banquet; joyous feast
Rare, formal term for a celebratory or auspicious banquet. Found mainly in literary or ceremonial contexts.
祝賀の佳宴が開かれた。
A splendid banquet was held in celebration.
Common word for 'banquet' or 'party'. 佳宴 is a much rarer, more formal and literary synonym.
Compound of 佳 (beautiful, excellent) or 嘉 (auspicious) and 宴 (banquet). The exact historical derivation is uncertain; the spelling is conventionally associated with celebratory feasts.
