Can I just comment on the way you've phrased your question? The logical answer to the question
'What does the Armenian word "Hadgohutyun" mean in English?'
'Nothing at all. "Hadgohutyun" means nothing in English, because it isn't an English word.'
What you should have asked is
'How do you say "Hadgohutyun" in English?'
'How would you translate the Armenian word "Hadgohutyun" into English?'
It means good luck and it means good bye also
or it means success.
It means "GOOD LUCK"
