- Geiss (Switzerland, Liechtenstein)
From Old High German geiz, from Proto-Germanic *gaits, from Proto-Indo-European *ǵʰayd-. Cognate with Dutch geit, English goat, Danish ged, Icelandic geit, Swedish get, Gothic 𐌲𐌰𐌹𐍄𐍃 (gaits); and with Latin haedus (“kid”).
Geiß f (genitive Geiß, plural Geißen, diminutive Geißlein n)
In standard German, the word is now widely restricted to southern Germany and Austria, although many dialects in northern and central Germany have also traditionally used Geiß or cognates thereof (compare Dutch geit). The derivative Geißbock (“billy goat”) remains somewhat more common than Geiß itself.
