κουδούνi would be the door bell and other smaller bells.. Here is my favorite dictionary link, there are 7 dictionaries all in one place. http://www.lexilogos.com/english/greek_dictionary.htm
Thank you. I don't think I have looked in the past, because I thought it was mainly about the keyboard, and I don't have any problem with that, especially since the Greek is clearly based on the qwerty keyboard.
Ok, just wanted to let you know. Yes, if you know qwerty there's very little difference. ψ,ξ and such. :-))
When I heard "bell" pronounced like "kabana", I wrote "καβάνα". So, when one combines Greek letters "μπ" you get a sound like "b"?
Go to the ABC skill and find the Tips & notes icon (top left on every page) there you will find the double consonants. As here "μπ" = b, "ντ"= d etc along with other important information. All skills (units) have Tips & notes.
