Questions & Answers about Днём датчик иногда реагирует на моё движение, и лампа включается просто так.
What exactly does Днём mean here, and what form of the word is it?
Днём means “in the daytime / during the day.”
Grammatically:
- The base noun is день (day).
- днём is the instrumental singular form of день.
- In Russian, the instrumental case is often used adverbially to express “at / during (a time of day)”:
- днём – in the daytime
- ночью – at night
- утром – in the morning
- вечером – in the evening
So Днём датчик… literally is “By day / During the day, the sensor…”, but in natural English: “In the daytime, the sensor…”
I sometimes see днем without ё. Is that the same word as днём?
Yes, днем and днём are the same word.
- The correct, fully marked form is днём (with ё),
- But in many printed texts, Russian ё is written simply as е, so you get днем.
Pronunciation is always with ё /dnyom/, not /dnem/. Writing е instead of ё is extremely common in Russian, especially in newspapers, books, and on the internet.
