Turkish basic course

I. -ecek değil
If we follow the suffix -ecek with any form of değil, we get a construction which differs from the plain negative in two respects:

3. 
   It is almost always a response or reaction to something said or implied just before.
   
4. 
   It is more emphatic. There is a hint of protest in it. The meaning may be thought of as equivalent to the phrase ‘I wasn’t expecting to...’, ‘I wasn’t intending to or planning to...’
   

Ben bu Cuma sinemaya gitmeyeceğim.

I’m not going to the movies this Friday.

This simply announces your decision not to go to the movies on Friday. There is an implication that you were expected to go to the movies, but this sentence is not a response.

Ben bu Cuma sinemaya gidecek değilim.

Don’t count on my going to the movies Friday, because I’m not.

Here there is a strong indication that the question of going to the movies on Friday has been brought up and the speaker is making it quite clear that he is not going.

Bir yere gidecek değilim!

I’m not going anywhere!

Such a response would be made if a friend said, ‘What a pity you won’t be in town, we could all have seen it together!’ Often there is a ki after değilim.

Bir yere gidecek değilim ki!
