Questions & Answers about Yol tıkandığı için henüz ofise gelmemiştir.
Why does gelmemiştir end with -tir here?
Adding -tir (or -dır, etc.) to the past tense -miş changes the meaning from a simple past action or hearsay into a logical assumption. While gelmemiş means "apparently he hasn't arrived," gelmemiştir means "he probably hasn't arrived." The speaker is making a strong guess based on the traffic jam.
Why do we say tıkandığı için instead of just using a normal verb like tıkandı için?
The word için (because/for) connects to nouns or noun phrases. You cannot put a regular conjugated verb like tıkandı (it jammed) right in front of it. Instead, we use the suffix -dık to turn the verb into a noun-like clause. Tıkandığı literally means "its being jammed," so the phrase means "because of its being jammed."
Why doesn't yol have the genitive suffix (yolun) before tıkandığı?
The strict grammar rule for -dık clauses says the subject should take the genitive case, which would make it yolun tıkandığı için. However, in everyday Turkish, the genitive ending is frequently dropped for general or inanimate subjects like yol (road). Both versions are perfectly correct and widely used!
