Questions & Answers about Gelenekler toplum için çok önemli.
Since this lesson is about göre, could I use topluma göre instead of toplum için here?
You could, but it changes the meaning! Topluma göre means "according to society" or "compared to society". The phrase toplum için means "for society". Notice that göre requires the dative case (topluma), while için just takes the plain noun (toplum) when used with regular nouns.
Where is the word for "are" in this sentence?
In Turkish, the present tense "to be" verb (is/are) is often just implied at the end of the sentence. You don't need to add anything to önemli (important) to mean "are important." Even though the subject gelenekler (traditions) is plural, the adjective doesn't need a plural ending.
Why is it toplum için instead of için toplum?
English uses prepositions (placed before the noun, like "for society"), but Turkish uses postpositions. These always come after the noun they refer to. So "for society" becomes toplum için.
How is the word önemli built?
It comes from the root noun önem meaning "importance". The suffix -li means "with" or "having". So önemli literally translates to "having importance", which we say as "important".
