New High German
The word "goose" is a direct descendant of Proto-Indo-European root, "ghans-". In Germanic languages, the root gave Old English "gōs" with the plural "gēs" and "gandres" (becoming Modern English goose, geese, gander, and gosling, respectively), Frisian "goes", "gies" and "guoske", New High German "Gans", "Gänse", and "Ganter", and Old Norse "gās".
