Peace,
Thanks for that Arnab. If that is all you can say that is fine. I see you didn't really show me how I was wrong (because i'm not) but just flatly stated I was wrong. But I don't have a problem with that I just hope you review what I've said and really consider the truth of it, I think I was clear enough. As for acquired meanings that is is all subjective. Obviously this meaning theoretically can only go back as far as Judaism goes among Arabs. I would agree in saying that it is most likely a borrowed word taken from Aramaic, Hebrew or even Greek and introduced by Arab Jews or Christians (but I admit this is an assumption even if it is the one most likely to be correct). Now how it came about from a central idea of 'support' is something we may never know. It could have been taken from some word spoken in the Jewish or Christians sphere (that leaves a number of options from Assyrian to demotic or archaic coptic or greek). Or it could be a concept derived from support like supproting the truth, faith, cementing one's faith, oath and dipping in water was the ritual representing that.(just like salat, having a meaning of prayer, has come to mean a certain ritual of prayer that most Arabs make. Arabic has a number of meanings of roots like that have take a sharp left turn and can be seen independent of the root even though that root meaning was its original point of origin. So let's not be blind to the fact that spin-offs of a root can evolve into totally separate meanings that don't seem to be connected to a essential root meaning.
And lastly if Huruf agreed with me on this issue then she saw the truth. Try to see the trees from the forest.
Godbless,
Anwar
