Questions & Answers about Утром я открыла шторы и увидела, что во дворе идёт снег.
Утром is the instrumental singular form of утро.
In Russian, some time expressions are commonly used in the instrumental case to mean during / in that part of the day:
- утром = in the morning
- днём = in the daytime
- вечером = in the evening
So Утром here simply means in the morning.
Using в утро would not sound natural in this everyday meaning.
Because the speaker/narrator is female.
In the Russian past tense, verbs agree with the subject in gender and number:
- masculine: открыл, увидел
- feminine: открыла, увидела
- plural: открыли, увидели
So я открыла and я увидела tell you that я refers to a woman or girl.
A useful thing to remember: Russian past tense does not show person the way present tense does. The form tells you gender/number, not I / you / he.
