Questions & Answers about На вулиці було десять градусів.
Why is there no explicit subject in this sentence, and why is the verb було used instead of були?
This is an impersonal construction common in weather and temperature expressions. Ukrainian uses the neuter singular past of бути (to be) – було – without any concrete subject. Even though “десять градусів” sounds plural, the verb remains neuter singular in impersonal statements.
Why is градусів in the genitive plural form instead of nominative or accusative?
In Ukrainian, numbers from 5 to 20 (and all tens like 30, 40, etc.) require the following noun in the genitive plural. Since десять (10) falls in this range, градусів (genitive plural) is grammatically correct rather than градуси or градус.
What case is на вулиці, and why is it used here?
На вулиці is the locative (also called prepositional) case after the preposition на. It indicates location (“on the street”/“outside”). For talking about being outside, locative with на is standard.
Could you use надворі instead of на вулиці? What’s the difference?
Yes, надворі is an adverb meaning “outdoors” or “in the yard.” It’s a bit more general or rustic, whereas на вулиці literally means “on the street” or “outside” in a public/open-air sense. Both work for “it was ten degrees outside,” but на вулиці is more neutral.
