Learn Turkish: Hükümeti desteklemeyen insanlar sonuç bekliyor. - The people who do not support the government are waiting for a result.

This word uses the negative subject relative participle. It breaks down into destekle (support) + me (negative marker) + y (buffer letter) + en (the participle ending meaning "who" or "which"). Put together, it describes the noun that comes right after it (insanlar), acting like the English phrase "who do not support".

Why does hükümet have an -i at the end?

The -i is the accusative case marker. Even though desteklemeyen acts like an adjective here, it is still an action at its core and needs a specific direct object. Because the sentence refers to a specific government, hükümet takes the accusative ending to become hükümeti.

The verb root for waiting is bekle, so why is it spelled bekliyor in this sentence?

When a verb ends in a wide vowel like e or a, and you add the present continuous suffix -yor, that vowel narrows. Following vowel harmony, the e at the end of bekle changes to an i, making it bekliyor.

The subject insanlar is plural. Why doesn't the verb have a plural ending like bekliyorlar?
