How to impress many, increase iq and meet and speak to more people?

Do you want to impress many, increase your iq or speak to more people?

If you answered yes to any of these questions, I believe learning another language or a word in a couple can help you. When you start a conversation the first word you would say is hello (to an unfamiliar person) or hi (to someone familiar). So the word for hello or hi or 'how are you?' would be good word to know in another language. 

Key:

(r) = rolled r

(rh) = guttural r

˜ = nasal sound
