Questions & Answers about Film başlar başlamaz telefonumu sessize alıyorum.

What does the structure in bold — başlar başlamaz — mean and how is it formed?

It means as soon as (it) starts. It’s a fixed temporal pattern built as:

• verb stem + aorist 3rd person singular + same verb stem + negative aorist
• In this sentence: başla-
  • r and başla-
    • maz → başlar başlamaz

Other common examples:

• gelir gelmez = as soon as (s/he) arrives
• görür görmez = as soon as (s/he) sees
• biter bitmez = as soon as (it) ends
• çıkar çıkmaz = as soon as (s/he/it) leaves/comes out
• yapar yapmaz = as soon as (s/he) does

Why does one part look affirmative (başlar) and the other negative (başlamaz)?

That’s inherent to the pattern. The combination “aorist affirmative + aorist negative” idiomatically yields the meaning the very moment that X happens. You don’t interpret the second verb literally as a negation here; it’s just how Turkish encodes “no sooner than.”

Could I use başlayınca instead? What’s the difference?

• başlar başlamaz = as soon as the film starts (immediacy emphasized).
• başlayınca = when/once the film starts (looser timing; not necessarily immediate).

Both are correct, but başlar başlamaz is stronger and sharper in timing.

Why is it alıyorum (present continuous) and not (aorist) for a habitual action?
