Breakdown of Когда она увидела подарок, она сразу улыбнулась.
Questions & Answers about Когда она увидела подарок, она сразу улыбнулась.
In Russian, a comma is required between a dependent clause and the main clause.
- Когда она увидела подарок – this is a dependent (subordinate) clause introduced by когда (when).
- она сразу улыбнулась – this is the main clause.
Rule: when the когда‑clause comes first, you must put a comma before the main clause.
You could also reverse the order:
- Она сразу улыбнулась, когда она увидела подарок.
You still need the comma.
Увидела is the past tense of the perfective verb увидеть. Perfective aspect is used for a single, completed action with a clear result. Here the important thing is the moment she noticed/registered the gift.
If you said:
- Когда она видела подарок, она сразу улыбалась.
this would sound like a repeated or ongoing situation: Whenever she saw the gift, she would smile.
So увидела fits better for one specific event that is completed.
