Learn Turkish: Altyapı arızası tamamen giderilmiş bulunmaktadır. - The infrastructure malfunction has definitively been completely resolved.

This construction (-mIş + bulunmak) is a highly formal way to express the perfect aspect, which is the focus of this lesson. While giderilmiştir just means 'has been resolved', adding bulunmak (literally 'to find oneself') emphasizes the current resulting state of the action. The malfunction 'finds itself resolved'. It sounds very official, which is why you will hear it in public announcements or formal reports.

I am having trouble recognizing the root of giderilmiş. Does it come from gitmek (to go)?

Yes! The root is gitmek. Adding a causative suffix turns it into gidermek (to make something go away, or to eliminate/resolve). Notice how the 't' softens to 'd' here. Then, the passive suffix -il is added to make giderilmek (to be resolved). Finally, the -miş suffix turns it into the perfect participle.

Why is there an -sı suffix on arızası?

This is a classic noun compound. Altyapı (infrastructure) and arıza (malfunction) are both nouns. To combine them into 'infrastructure malfunction', Turkish requires the possessive compound marker -(s)ı on the second noun, making it altyapı arızası.

What role does the -dır suffix play at the very end of bulunmaktadır?
