Questions & Answers about Cevap kâğıdı masanın üstünde.

What are the main parts of Cevap kâğıdı masanın üstünde?

It has two main parts:

• cevap kâğıdı = answer sheet / answer paper

A more literal breakdown of the second part is on the top/surface of the table.

Why is there no word for is in the sentence?

In Turkish, the verb to be is often not expressed in the 3rd person present tense.

So instead of saying something equivalent to The answer sheet is on the table, Turkish simply says:

• Cevap kâğıdı masanın üstünde

This is completely normal.
The idea of is is understood automatically.

Is the -ı in kâğıdı the accusative ending?

No. Here, -ı is not the accusative.

In cevap kâğıdı, you are looking at a very common Turkish structure called an indefinite noun compound:

• cevap = answer
• kâğıdı = its paper / sheet

Together, this means answer sheet or answer paper.

So the -ı here is the compound/possessive ending that appears on the second noun in this kind of construction, not the direct-object marker.
