Do the words Wave(English) Welle(German) Vague(French) have the same Etymology as Val(Serbo-Croatian,Slovenian),Vlna(Czech,Slovakian),BолнаVolna.
All these words mean the same thing-Wave. but I found it surprising, given their relative similarity, that they have a different Proto-Indo-European root.
Wave/Welle comes from the Inde-European *wegh where Val/Vlna comes from *wel
Can anyone explain why these word that mean the same thing and are so alike still do not have the same etymology?
