Questions & Answers about Ребёнок сидит на ступеньке.
In Russian, every noun has a grammatical gender (masculine, feminine, or neuter). This is a property of the word itself, not of the real person or object.
- Ребёнок is grammatically masculine.
So any verb or adjective that refers to ребёнок will also be in masculine forms:
- маленький ребёнок сидит – a small child is sitting (маленький = masculine)
- уставший ребёнок – a tired child (уставший = masculine)
If you specifically want to say whether the child is a boy or girl, you would normally use мальчик (boy) or девочка (girl), which are also grammatically gendered (masculine and feminine, respectively).
The infinitive of сидит is сидеть – to sit, to be sitting.
Form сидит is:
- 3rd person singular
- present tense
- imperfective aspect
So сидит literally means:
- he/she/it sits
or, in natural English: - he/she/it is sitting
In Russian, the simple present (сидит) usually covers both English “sits” and “is sitting”, depending on context.
