Looking for the connection of Yetzer and the translation as inclanation, I was surprised that almost every Hebrew word derived from the same root had to do with creating.
So how did a word (from a root with a common denominator of creating) begot the meaning of inclination?
Information I found based on etymology:
The word yetzer יצר is related to the verb yatzar יצר which means something like 'to create, fashion, produce or form'.
But within the Etymological Dictionary of Biblical Hebrew by S.R.Hirsch I found a nice reference to the Aramaic word yitzra יצרא which according to Hirsch means inclination.
But other translations of what seems to be the same word (איצרא) in phrases like yitzra d'ervah and yitzra d'avodah zarah translate it as tempter, urge, intent, drive.
Are there any commentaries that show the connection?
