Umm he said merhaba which means hello. I gues he has started learning Turkish, or only googled
it. 
i'm trying to learn Turkish, but it's hard as hell D:
Believe me, Turkish and Arabic will be VERY hard to learn for most speakers of the Latin successor languages.
It's actually easier for me to learn Turkish since it has many similarities with Arabic (lots of words derived from Arabic and quite a number of Turkish words used in Arabic). Like the words Lutfen (Turkish) and Tfaddal (Arabic) mean the same thing, but they don't have a literal translation to English (closest thing you'll get is "Please", "Have a seat", "Help yourself", etc).
Fun fact: Arabs say "Tuz" in a derogatory way which roughly means "Screw it" more or less, but in Turkish the word means salt. They say this is because people who carried salt around had to go through various checkpoints throughout the Ottoman Empire, and eventually got sick of it. So when asked what they're carrying, they'd say "Tuz!" in an annoyed manner, and it just sort of caught on later.
