I'm pretty sure Armenian is still supposed to be in the Indo-European family... Which... well, I didn't understand your attitude towards your intelligence, to be frank. Which is a complicated topic anyway...

I think my current language learning spree had a bit to do with the fact that I couldn't understand how people decided that some languages were related to others... I think I'm finally starting to get it.

Like, they say that the fact that the number "three" is the same in Latin, Slavic and Celtic langages matters. But why? Because that's a part of speech that generally won't get borrowed from a different language. The same with pronouns... Words that tend to get borrowed are nouns and verbs, coming over together with the foreign objects and activities...
