Questions & Answers about O kadar yorgunum ki konuşmak bile istemiyorum.

What does the structure “o kadar … ki” mean in this sentence?

O kadar … ki is a common Turkish pattern meaning “so … that …”.

• o kadar yorgunum → I am so tired
• ki introduces the result of that degree: that I don’t even want to talk.

So the whole structure is:
O kadar yorgunum ki … → I am so tired that …

What is the role of “o” in “o kadar yorgunum ki”? Is it “he/she/that”?

Here o is not a pronoun like “he/she”; it is part of the fixed expression o kadar.

• kadar on its own can mean as much as / up to.
• o kadar together means “that much / so much”.

So:

• yorgunum = I am tired.
• o kadar yorgunum = I am that tired / I am so tired.

You would not normally say ∗kadar yorgunum without o; o kadar is the natural phrase.

Why is it “yorgunum” and not just “yorgun”? What does -um do?
