I don't have a greek keyboard
Please check the sticky FAQs post here https://www.duolingo.com/comment/23799672.
Who says this?
Anyone who wants to decline politely. ;)
I often type ο instead of ω or η instead of ι... or misplace ´... but it will still be considered "correct." Will it become more sensitive?
I assume it can be meant for speach, as ω-ο sound the same just like η-ι altough i know ω is mostly used at the end. Πάω εγώ έχω
Is no please what you would say instead of no thankyou in greek?
No, thank you = Όχι, ευχαριστώ
No, please = όχι, παρακαλώ (as in No, please, there is no need to do that, I can do it on my own)
Is it "δεν" or "οχι"?
It's όχι because δεν means 'not' and has to be followed by a verb.
What is the literal meaning of παρακαλώ?
