Some phonological observations

Perhaps only interesting to a linguist, but I've noticed that Greek makes no phonemic distinction between \nd\ and \d\; or between \ng\ and \g\.  This means a Greek usually can't hear the difference, say, between "Woody Allen" and "Woondy Allen" ("Woody" is spelled Γούντι in Greek).  On the other hand, they *do* make a phonemic distinction between \k\ and \χ\, and between \g\ and \γ\.  I can usually hear the difference, but can only produce the \χ\ and \γ\ sounds with difficulty.  As Spock would say: fascinating.
