Semitic *gam(a)l- 'camel' is a widespread word which designates the dromedary of SW Asia and North Africa, first domesticated in Arabia before 2,000 BCE1, and was borrowed into Greek kámēlos and in turn into Latin camēlus.
This appears to be a Wanderwort which originally designated some wild ungulate of the Eurasian steppes and which is also found in Baltic *kumel-iā̃, Slavic *kobɨ̄lā 'mare' and in Altaic (with metathesis): Turkic *Kulum 'foal', Mongolian *kulan 'ass', Tungusic *ku(l)ma- 'maral (Siberian stag)' (EDAL 911).
