Önce yemeceğim o zaman işe gidiyorum. I will eat first then go to work. I am really looking to understand and apply the use of "then" in Turkish, just as we use it in English.

 Thank you

Did you want to have it translated to Turkish?

Önce yemek yiyeceğim, ondan sonra işe gideceğim. My attempt.

Thank you Melek

 i think you can use ..... yemek yiyip....

afferin sana

 Yes, if you will go straight out to work as soon as your meal is finished.

Yemek yiyip işe gideceğim implies the second is immediately following.

sonra işe gideceğim implies the second will happen sometime soon after the first, but you might stop to catch your breath in between!
