Learn Hardcore Turkish: Bilgisayar donunca ekran paylaşımı da kapandı. - When the computer froze, the screen sharing also closed.

The suffix -ınca/-ince/-unca/-ünce makes a time clause meaning when/once/whenever. It’s attached to the verb stem (here don- “to freeze”) and follows vowel harmony, so with the back rounded vowel it becomes -unca: don + unca → donunca.

Can I say donduğunda instead of donunca? What’s the difference?

Yes. Donduğunda also means “when it froze.” It’s built with the nominalizer and a locative: don + duk + 3sg poss -(u) + (n)da → donduğunda. Both are correct; -ınca is a bit more colloquial/compact, while -DIĞINDA can sound a tad more formal or specific in timing.

What about donduktan sonra?

Donduktan sonra means after it froze, stressing sequence more explicitly. -ınca often implies near-simultaneous or triggering timing, while -dıktan sonra is “after X (then Y).”

Does donunca imply cause, or only time?

Primarily time (“when/once”), but in real usage it often carries an implicit causal feel (“As/Once the computer froze, …”), especially when the main clause is a direct consequence.
