Thanks for all the help so far.  I really think I´m making better progress because of this website. I had a question about a few phrases and difference between them which should be used. 

Example: Adam arbanın içinde.  VS statements like.  Adam mutfakda. 

I know its mostlikely something simple and I´m overlooking it but i cant seem to get my brain to work today lol. ( I think I may know the difference but I would like to be sure so I will learn correctly.)

Thanks in adavance.

Sorry I forgot the word mutation for the Consonant Harmony

Adam arbanın içinde.  VS statements like.  Adam mutfakta.

Is there a question there somewhere?

Anyhow:

Adam arabanın içinde. = Adam is in the car. (you can say "Adam arabada.")

Adam mutfakta. = Adam is in the kitchen.

Adam means "man" in Turkish. Since there was no context, I don´t know if it´s a name or not...

 Adam arabanın içinde seems a bit odd to the ear. It is like saying "the man is inside the car" instead of "the man is in the car".

It would only make sense as a response to "Is the man standing by the car?" "No, he is inside the car."

Thanks for the great explanations . This really helps me alot.
