IPA: /ˈɡreɪlæɡ/
KK: /ˈgreɪˌlæɡ/
A type of wild goose found in Europe, known for its gray feathers and often considered the ancestor of many domestic geese.
The greylag is often seen swimming in the lakes during the spring.
Greylag is formed from "grey" (from Old English "grǣg", meaning of a dull color) and "lag" (from Old Norse "laga", meaning to lay or to lie). The term refers to a type of wild goose that is grey in color and often found lying or resting in fields.
Think of the dull color 'grey' and the idea of something 'lying down' — that's how 'greylag' describes a grey goose that often rests in fields.
