>by the time when Y has been added to the Latin alphabet Note also that the letter 'Y' is explicitly named 'Greek I' [literal translation] in Latin-descended languages; and then other languages borrowed that name (from the French). It's not called that in English, of course, but English isn't a Latin-descended language. Interestingly, the same is not true for 'Z', which is a more direct 'zed' (or 'zet', not like 'd' and 't' are that different) in most (all?) European languages, including the Germanic ones.
