Merhaba, 

I have 2 examples:

1. Bardağı(did you mean bardak-glass? ) masanın üstüne koy.
  Put the glass on the (top of) table.

2. Kitabı masaya koy. 

  Put the book on the table.

i think, this isnt wright (in my examples)

Can somebody help me, please?

It´s imperative way of the verb koymak-to put.
