ritual donation; offering made at a ceremony
Refers to a monetary or material contribution given during a religious or ceremonial rite, such as a Shinto festival or Buddhist memorial service.
I made a ritual donation at the shrine's annual festival.
Compound of 祭祀 (さいし, 'ritual, religious service') and 料 (りょう, 'fee, charge'). The exact historical derivation is uncertain, but the word is transparently formed from these elements.
