Excuse me, but I do not like they way you are minimizing Western Armenian which is spoken by the majority of Armenians in the world. Eastern Armenian is the official dialect in Armenia, and is spoken also in Iran and former Soviet Union. Everywhere else it's Western Armenian and there is no necessity (the way you put it) of speaking Eastern Armenian.Oh, I didn't see your link before, clevermizo. Then a word "bayergun" is really seemed as "good evening". In Armenian is:
Բարի երեկո or Բարի իրիկուն (bari yereko or bari irikun), Բարի - Good, երեկո and իրիկուն are synonyms and mean "evening".
And You say "Eastern dialect", but it isn't just a dialect, but official Armenian language. And there is a Western Armenian dialect which is used in the USA, Western Europe etc.
Armenians have various accents and vocabulary depending on which country they live in. The ones in the Middle East, for example, say "yalla" all the time.Thanks everybody. I think the pronunciation reflects that they are heritage speakers and that Arabic not Armenian is their first language.
