How I will say : 
I won´t go out
But with verb: dışarı çıkmak

Thank´s in advance..  

my attempt

dışarı çıkmayacağım

Thanks!!!!
And how is it for Positive?
I will go out..
Is that Dışarı çığacağım ? 

No, the first ´k´ does not mutate to ´ğ´

çıkacağım

1)Tamam,teşekürler ! Is that rule applies in every words,or just in this?
2)End second question. How it´s saying : 
Defol or Defolup ?

My understanding is that when a noun ends in a ´K´, and a suffix that starts with a vowel is added, then the mutation occurs.

For example kopek - kopeğim (my dog)

But, for verbs, the verb root that ends in a ´k´ does not mutate when a suffix that starts with a vowel is added.

eg çıkmak - çıkıyorum, çıkacağım 

You would say ´defol´

It comes from ´defolmak´

Defolup would be used with another verb following it, like

nihayet defolup gittiler! 

I clear understand now! Thank you so much!

Thank´s for this also. I heard it in series,but it wasn´t be clear how it´s writting,but i understand!  

Henry you rock. Bravo. Brilliant explanations.
