Learn Turkish: Bu kazak şu ceket kadar kalın. - This sweater is as thick as that jacket.

In Turkish, to say 'as [adjective] as', you use the pattern '[Noun] kadar [adjective]'. Here, şu ceket kadar kalın literally means 'that jacket as-much-as thick'. You do not need an extra word for the first 'as' like we do in English.

Why is kalın at the very end of the sentence?

Turkish structures comparisons differently than English. The subject comes first (bu kazak), then the thing it is compared to (şu ceket), followed by the postposition kadar, and finally the adjective kalın describing them both.

What is the difference between bu and şu in this sentence?

bu means 'this' for something very close to the speaker. şu means 'that' for something a bit further away, or something you are specifically pointing out to draw attention to it. The speaker is likely holding the sweater (bu kazak) and pointing at the jacket (şu ceket).

Where is the word for 'is' in this sentence?

In Turkish, the 'to be' verb for the third person singular ('it is') often has no visible suffix. The sentence just ends with the adjective kalın (thick), and the 'is' is automatically understood.
