My samsung keyboard can not write Greek alphabets. That is why I could not pass the writting trail.
With all due respect "Ναι, ευχαριστώ" is indeed a polite reply but literally, it means "Yes, thank you" and as a teaching course we need to be precise. Thank you for your input.
I agree with salvatore. Since ω is a double o it technically doesn't need an accent cuz it's pronounced as a long o. In fact, back in classic Greek the lower case ω was often written with the infinity sign(∞) in handwritten documents. Because, again, ω is a double o. So in words where the accent is above ω it isn't necessary because ω already ought to be pronounced like a long o and accents are really only required when the emphasis is to be put on a different letter.
