This is the 1482nd most frequent Russian word.
написала
"Написала" means "wrote" (feminine, past tense).
The word "написала" here is the past tense form of the verb "писать" (to write) in the feminine singular, indicating that the subject (I) is female and performed the action of writing in the past.
Я написала письмо.
I wrote a letter.
In this sentence, "написала" is again the past feminine singular form of "писать," used to describe an action performed by 'she' in the past, specifically writing on the board.
Она написала на доске.
She wrote on the board.
Although the verb form "написал" is being used, it is in masculine singular form because Russian defaults to masculine for questions if the gender of the subject is unknown. This showcases gender agreement’s flexibility in questions.
