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

I think you should use ´ den/dan sonra´ here (meaning ´after) and say ´Yemekten sonra (after eating) işe gidiyorum/gideceğim (I will go to work)´  Slightly different phrasing but same meaning.

My attempt 

 You are right,LIR. But we do´t use -den/-dan with sonra all the time.

I will eat first= önce (yemek) yiyeceğim

then go to work = sonra işe gideceğim

 Just a couple more corrections.

yemeceğim: no such word.

Yemek: food

Yemek: to eat. This then takes the form:

yiyeceğim: I will eat

yemeyeceğim: I will not eat.

"o zaman" can mean then, but it is more usual for "in that case". Like "yağmur yağıyor",dedi "O zaman parka gitmeyelim", dedim. He said "it is raining", I said "Let´s not go to the park, then"

.

 I think that suffix is used for and

Çok teşekkürler Upsy daisy.

I noticed:

Roma´da bir hafta kaldıkdan sonra Nepal´a gittik.

Was this a typing error or not? I assume it is

Roma´da bir hafta kaldıktan sonra Nepal´a gittik.

 Ah! you caught me typing a mistake. Yes, it is "kaldıktan", not "kaldıkdan". But you know what? Pronounce the word as "kaldıkdan" is easier than to pronounce it as "kaldıktan" which is the correct form according to the vowel harmony.

 Sorry to say Turkaturk but -ip doesnt mean ´ then´ nor ´´after´´

Here is from Teach Yourself Turkish:

   Ïn English instead of saying ´´Tonight Im going to have a bath and im going to wash my hair´´ you can say ´´ Tonight im going to have a bath and wash my hair´´. The second ´´ im going´´ is not necessary so we miss it out without losing the meaning.

   In Turkish you can do things similar but here where you miss a  bit out you insert a signal to let people know you´re skipping something: - ip ending.

Bu akşam banyo yapacağım ve saçlarım yıkacağım.

Bu akşam banyo yapıp saçlarım yıkacağım.

.

For me is not confusing at all this -up ending. Go to Teach Yourself Turkish by A. and David Pollard at chapter 12 . There is very nice explained.

Bu akşam banyo yapacağım ve saçlarım yıkacağım.

Bu akşam banyo yapıp saçlarım yıkacağım.

Here these  2 actions how happen ? One after other ? Or the same time ?

.

Better  work´´-up´´  on that hang around here 

kafam karıstı

  kafanı karıstırma ! 

 .

Well i used -ip..ending for saying : ´´better work  on that and hang around here ´´

after, i think...

i saw this -ip -up thing first time in WinMekMak and there it´s still kalkıp = stand up and...gidip = go and...so you first stand up and then do smth else, you first go and then do smth else...1 action is coming AFTER the next one...and i´m still using this WinMekMak for practicing conjugations etc, so far it hasn´t let me down yet

-ip ending is used for avoiding repetition . Not because something happens before or after. My opinion..

right coz think about it if i say kalkıp gidip uyuyacağım without those -ip suffixes it would sure repeat i will stand up and i will go and i will sleep

.

I understand it..i can use it..but i will never use it instead of ´´then´´. Thats all. In the book is well enough explain. Its not about how good is your turkish teacher..but how its explained the -ip ending in english.

I know i used it in the previous translation request  only because in that day ( yesterday i think ) i had an obsession of using it

I dont think this is corect:

1. Yemek yemeyip işe gideceğim.

Because the first verb is at the negative form...and both has to be at same form of the verb.

If someone can confirm it.....

 Yemeyip mean "without eat" we are using that kind of words in daily life. By the way it doesnt has to be at the same form. One sentence whilst affirmative, connection sentence can be negative.

Here is a native that wants to help you

It is mostly used when one thing is happening after another. However in this case you also use "and " in English, not always "then"

e.g.: Kahvaltı yapıp evden çıktım. I had breakfast and left home. OR I had breakfast and then left home . (even if you don´t use"then", you know breakfast was the first action)

You can also understand that two things are not happening at the same time if you swtich the position of "-ip"

i.e.: Evden çıkıp kahvaltı yaptım. I left home and (then) had breakfast. (obviously I did not have my breakfast at home)

The thing confusing you is that we also sometimes use it for spontaneous actions!

Although "-erek, -arak" is more suitable in this situation, "-ip" is also used!

e.g.: Mısır yiyip film seyrettik. We watched a movie while eating popcorn./We watched a movie and ate popcorn.

OR

Mısır yiyerek film seyrettik.

finally ,some senseoh are you DEFINITELY sure of this

Thank you Dilli 

I think I should definitely be sure, since I am speaking this language now for 23 years 

 Many happy returns

 I wonder if the information above only depends on you having been speaking the language as a native for 23 years, or it is from books used in general education curriculum, reliable sources, linguistic articles and so? Can you cite some sources  supporting your point?
