Learn Turkish: Kulaklarım soğuk.

The buffer n is only used after a third person possessive suffix (meaning his, her, its, or their) when you add a case suffix (like in, on, or to) right after it. Here, we have the first person possessive -ım (my) and no case suffix, so we don't need a buffer letter.

What is the exact breakdown of the suffixes in kulaklarım?

It breaks down as kulak (ear) + lar (plural) + ım (my). In Turkish, the plural suffix always comes before the possessive suffix. You are literally saying "ear-s-my".

I thought words ending in 'k' usually change to 'ğ' when we add a suffix. Why did it stay as kulak?

That rule (consonant mutation) happens when the suffix you are adding starts with a vowel. The very first suffix we add to kulak is the plural -lar. Since -lar starts with a consonant, the k doesn't change. The vowel in the possessive -ım comes later, attaching safely to the r in -lar.

Where is the word for "are" in this sentence?

In simple Turkish sentences, "to be" (am/is/are) is usually attached as a personal suffix at the very end of the sentence. However, for third-person subjects (like "he", "she", "it", or "my ears"), you can often just leave that suffix off entirely. Kulaklarım soğuk is a perfectly complete sentence just the way it is!
