Learn Turkish: Hava çok kötüydü; dolayısıyla uçuş iptal edildi. - The weather was very bad; consequently the flight was cancelled.

Yes! The current sentence links two separate thoughts with dolayısıyla (consequently). To use yüzünden (because of / due to), you would combine the ideas into a single sentence: Kötü hava yüzünden uçuş iptal edildi (Because of the bad weather, the flight was cancelled).

How exactly does dolayısıyla translate to "consequently"?

It is built from the postposition dolayı (due to / because of), the possessive suffix -sı, the buffer letter -y-, and the instrumental suffix -la (with). Literally meaning something like "with its due-to," it functions as a conjunction meaning "therefore" or "consequently."

Why does the sentence use edildi instead of just etti?

The verb iptal etmek means "to cancel." Since the flight didn't cancel itself—it was cancelled by someone—we need the passive voice. The helping verb etmek becomes edilmek in the passive, and adding the past tense -di gives us iptal edildi.

What is the -y- doing in kötüydü?
