Hello you all. I would like to explain something about the pronounciation of the ypsilon in Ancient Greek. If the sound is used as a vowel, that is, not formig a diphtong, it is pronounced similar to a French u, a sound between the u and the i /ü/. But if the ypsilon forms a diphtong, it sounds like a u, so eu /eu/, au /au/ and the exception is ou /u/. In Homer the diphtong eu can be pronounced in two different sounds, if there's diaeresis and not a diphtong. The situation of the spiritus and the accent indicates when the two vowells are pronounced together or separately.
