Wow, it took a long time and lots of web pages to register so I can ask this question, so I hope I get an answer. <smile>
I saw this
Mitko: Добър ден.Аз се казвам Митко(Димитър).
That first sounds to me like the Russian greeting, so I expect it is just as it sounds.
But, I saw this as a translation on a program for the "OK" button, for Bulgarian:
Why does that function for "Ok" -- is it part of Добър ?
