Hi Spiro
It's not clear from your answer whether these are the sounds that are only used for these letters, ie would they be understood by everyone. Also, it's not clear what the sounds are for other letters.
I suppose my question is this: is there a systemetic, albeit informal or jocular (and I would like to know which), way of prononuncing abbreviations (not acronyms, which by definition are abbreviations that can be read out as words).
In other alphabets, the names of letters are very short, ussually one syllable. In Greek, they are often three syllables. I find it hard to believe that there isn't a shorthand systematic way of pronouncing letters like epsilion, omicron, ypsilon, kappa, sigma, omega, etc.
Nickel - you indicate that for consonants, you add -ou systematically and that the register is v informal. I would like to know the rules if you have the time to explain.
