Are there common root of words Σύγχυσις "Babylon" and συναγωγὴν "gatherings" in Greek?
Some say that the Greek Alphabet was taken from Phoenician. So, is the Greek Upsilon (Y) is Phoenician Waw-letter (Y)? If it is so, then the word "synagogue" must be pronounced like [sawnagogue] like [oo]-sound.Greek Υ was pronounced like German ü from classical times and probably until the 10th century. Earlier it was pronounced like German u and maintained that sound in other (Doric or Aeolian) dialects; there are even indications that it may have been pronounced like Eglish u in 'mule' in some places. But by Roman times, there is no doubt it was pronounced like German ü, a sound which Latin lacked; that is why a special letter was added to the Latin alphabet to represent that spund in loanwords from Greek. Only the educated Romans pronounced it that way, of course; the masses pronounced it a simple i, which is how y ended up as just another letter for i in most European languages.
