Hi! In Arabic, غراب ghurab (or ghorab) is used for different types of crow (and magpie). I wonder if it has any relation to IE words like crow (En), corbeau (Fr) and cuervo (Es)? Or is it just deriven from the animal's sound? Or is it another word by غ.ر.ب (gh-r-b) root related to غروب (sunset) or غریب (strange)? Thanks.
