Learn Turkish: Düşenler dublör mü? - Are the ones who fall stunt doubles?

This is the core of this lesson! The verb düşmek (to fall) gets the subject participle suffix -en, becoming düşen (who falls). Usually, this describes a noun, like düşen insanlar (people who fall). But if we drop the noun, we can add the plural suffix -ler directly to the participle. So düşenler literally means "those who fall" or "the falling ones."

If we wanted to include the word "people", how would this sentence change?

If you don't omit the noun, the plural suffix moves to the noun. You would say Düşen insanlar dublör mü? (Are the people who fall stunt doubles?). You cannot say düşenler insanlar because the participle düşen acts as an adjective here, and adjectives don't take plural endings when they sit next to a noun.

Why doesn't dublör have a plural suffix if we are talking about multiple stunt doubles?

In Turkish, when the subject is already clearly plural (like düşenler), you don't strictly need to make the predicate noun plural too. Saying Düşenler dublörler mi? is grammatically okay, but it sounds a bit repetitive. Turkish prefers to keep it simple with Düşenler dublör mü?

Why is the question word mü instead of the usual mi?
