The assumption would be, were it true, that all words beginning with "wr" would have some sense of twisting.

Why is "all", or even "most" a necessary condition, Capfka?

You would only expect to see such a dominant pattern if the pattern was systematically imposed from above, rather than intermittently, but persistently, from below.

I truly don't know where you are digging up your "Old English roots", Capfka, but I suspect there was no rule book around when those roots were planted.

I can understand why you guys would want to pull all this square root of PIE business on me, but is it fair to pull it on IsIsIs?
