Breakdown of Я не могу не улыбаться, когда эта певица начинает свою первую арию.
Questions & Answers about Я не могу не улыбаться, когда эта певица начинает свою первую арию.
This is a very common Russian pattern:
- не могу = I cannot
- не улыбаться = not smile
Together, не могу не улыбаться literally looks like I cannot not smile, but in natural English it means:
- I can’t help smiling
- I can’t help but smile
So this is not a mistake or a double negative that cancels itself out in the English way. In Russian, this structure is standard and expresses that something is impossible to resist.
Because улыбаться is the imperfective form, and it focuses on the process or repeated action of smiling.
Compare:
- улыбаться = to smile, to be smiling, to keep smiling
- улыбнуться = to smile once, to give a smile
In Я не могу не улыбаться, the idea is not just one quick smile. It suggests an ongoing or automatic reaction: whenever this happens, the speaker ends up smiling.
So улыбаться fits better than улыбнуться.
