Skein
collective noun /skeɪn/ — Geese in flight — stretched across the sky in a thread of movement.
Definition
The collective noun for geese in flight, typically arranged in a V-formation. The word is borrowed from the bundled thread of yarn it resembles in the sky.
Beyond the definition
A skein of geese across an autumn sky is one of those sights that catches the breath. There's something about the formation — purposeful, ancient, together — that feels meaningful in a way that's hard to articulate.
Origin & history
From Old French escaigne — a hank of thread or yarn. When geese fly in formation, seen from below or against the sky, they resemble a loose thread being pulled across the horizon. The image is visually precise.
