Questions & Answers about Когда шов снова стал ровным, я поняла, что старая куртка ещё пригодится.
After verbs like стать / становиться (to become), Russian often uses the instrumental case for the word that describes the new state.
So:
- шов стал ровным = the seam became even/smooth
Compare:
- Он стал врачом = He became a doctor
- Она стала спокойной = She became calm
You may sometimes see nominative after стать in informal speech, but instrumental is the standard choice.
The verb here is стать = to become. It is not reflexive.
So:
- шов стал ровным = the seam became even
The ending -ся appears with many Russian verbs, but стать in this meaning does not take it.
