Learn Turkish: Rüzgâr soğuk esse bile kışlık kazaklarımız bizi sıcak tutuyor. - Even if the wind blows cold, our winter sweaters keep us warm.

The verb root es (from esmek, to blow) takes the conditional suffix -se, giving us esse (if it blows). Adding the word bile (even) right after it creates the concessive conditional. Together, esse bile means "even if it blows."

Is soğuk an adjective or an adverb in this sentence?

It is an adjective acting as an adverb. In Turkish, you can often use an adjective like soğuk (cold) directly before a verb to describe how the action happens, without needing to add any special suffix. So soğuk esse simply means "if it blows cold."

What is the function of the -lık suffix in kışlık?

The suffix -lık (and its vowel harmony variations like -lik, -luk, -lük) creates adjectives that mean "suitable for" or "intended for." Since kış means "winter," adding -lık makes kışlık, meaning "intended for winter."

Why do we use bizi instead of just biz before sıcak tutuyor?
