Questions & Answers about На вулиці темно.
Literally, На вулиці means “on the street” and темно means “dark”. As a whole, the sentence is an impersonal statement best rendered in English as:
• “It’s dark outside.”
вулиці is in the locative singular of the feminine noun вулиця (street).
• The locative case in Ukrainian shows location (“where?”).
• After the preposition на (on), we use the locative to say “on/at” a place: на + locative → на вулиці (at/on the street).
темно is the short-form neuter singular of the adjective темний. In impersonal sentences expressing general states (weather, time of day, feelings), Ukrainian uses:
• No grammatical subject
• A predicate in neuter form
Thus темно functions like an adverbial predicate: “(It is) dark.”
