How to Say Happy Birthday in Turkish

İyi ki doğdun. In Turkish the letter "ğ" means lengthen the o and the u and merge them into one. It doesn't have a sound of its own, though. This is pronounced eey-ki dough-doon. The oo is like the oo in book. The gh must be very soft, like the gh in "Bread Dough". The basic meaning of this is "It's a good thing you were born."

Mutlu yıllar. In Turkish, the letter "ı" is like a cross between the u in umbrella and the oo in book. It is pronounced moot-loo yull-larr. In this one, trill the r. The oo is, again, like the oo in book. The basic meaning is "Happy years." This need not necessarily be limited to birthdays, though.

Doğum günün kutlu olsun. The ü is the oo in book leaning over just a bit to sound like ee. Again, the ğ makes a soft gh sound, like the gh in Bread Dough. This is pronounced do-wum goonoon kootloo olsun. The basic meaning is "May your birthday be celebrated."
