In Turkish, it is really difficult to translate some phrases because some of them could be classified as idioms, but some of them are just one word. The words have special meanings and are not used in any other words. Some words come from Arabic, but Turkish culture is effected by Islamic culture.
Hoşgeldin: This word is said by the owner of the house or place when someone comes to their properties. It may be translated as “good you come”.
Hoşbulduk: This word is said by the person who comes to someone’s property to the owner of the house or place. This means “we found ourselves good here” and is a kind of response to Hoşgeldin.
Maşallah: This word is Arabic and directly taken from Arabic because it has the name of Allah (God). When someone sees a great thing or a person, s/he says Maşallah to them as “Wow! That’s great!”.
İnşallah: This word also comes from Arabic and it means “God willing”. This is used in situations that you want to be happened.
Allah Korusun: Literally, these words might be translated as “God Bless you”, but instead of saying it, it has also a meaning which is “May God Protect you”.

Hoşça kal: When you leave from an apartment or office or somewhere else, people say each other Hoşça kal. It means “Be Fine” or “Stay Fine”.
Kendine iyi bak: These world might literally be translated as “Look yourself Good”, but I think “Take Care” is the best translation for this phrase.
Kolay gelsin: Actually, I wish there is word that has the same meaning with this word in English. I used to say this word everywhere before I came to the US. For example, if you go to market, bakery, grocery, or somewhere else that people work, you can say this phrase to them as “Take it easy”, but it does not have the meaning with “Take it easy”.
Çok Yaşa: When someone sneeze, this word is said by people. Instead of having the same meaning with “God Bless You”, this phrase means “Live Longer”.
