Questions & Answers about Когда я чувствую сильную сонливость днём, я стараюсь немного поспать.
Сонливость means sleepiness or drowsiness as a state, not just “being tired.”
- сонливость = a persistent feeling of wanting to sleep / drowsiness
- усталость = tiredness, fatigue (you can be усталый even without wanting to fall asleep)
- (я) хочу спать = “I want to sleep / I’m sleepy” (a direct statement, more colloquial)
So сильную сонливость is “strong drowsiness / very sleepy feeling,” focusing specifically on the urge to sleep, not just low energy or general fatigue.
Сонливость is a feminine noun (like мать, ночь, жизнь) ending in -ость.
- Base (nominative) form: сонливость (feminine)
- In the sentence it is the direct object of чувствую (“I feel”), so it must be in the accusative case.
- Feminine nouns in -ость have the same form in nominative and accusative: сонливость.
- The adjective сильный must agree with it in gender, number, and case:
- feminine, singular, accusative → сильная → сильную
So we get сильную сонливость = “strong sleepiness” (object of “I feel”).
