first offering of the season
Original meaning: the first harvest or catch offered to the gods. Now rare and mostly historical; the modern word is usually associated with the shrike behavior.
In old texts, はやにえ referred to the first seasonal offering to the gods.
Rare kanji spelling; 速 means 'quick' and 贄 means 'offering', but this form is not common.
Irregular kanji usage; 早 can mean 'early' but this spelling is not standard.
From 早 (haya, 'early') + 贄 (nie, 'offering'), originally meaning the first offering of the season. The modern meaning derives from the shrike's habit of impaling prey early for later consumption.
