Learn Turkish: Trol üç saattir herkesi kışkırtıp duruyor. - The troll has been continuously provoking everyone for three hours.

This uses the pattern for continuous repetition: Verb stem + -(y)Ip + durmak. The verb kışkırtmak (to provoke) drops its infinitive ending and takes the -ıp suffix to match its vowels. Then we add duruyor (is keeping / stands). Together, kışkırtıp duruyor means the troll keeps on provoking people without stopping.

Why is the suffix -tir added to saat?

The suffix -dir (which becomes -tir here due to consonant harmony with the voiceless 't' in saat) is attached to time expressions to indicate duration, translating to "for" in English. Üç saattir means the action has been going on for three hours and is still happening right now.

Why does herkes (everyone) take the -i suffix here?

Herkes is the direct object of the verb kışkırtmak (to provoke). Because words like "everyone" are inherently specific, it requires the definite accusative case. Adding the -i makes it herkesi, showing exactly who is receiving the action of being provoked.

Is kışkırtmak mostly used for physical provoking or emotional instigating?

It usually means to incite, instigate, or stir up trouble emotionally or socially. It perfectly describes what an internet troll does when they try to make people angry or start arguments in a comments section!
