Questions & Answers about На балконе натянута верёвка, и на ней сохнет бельё.
Because на can take different cases depending on meaning:
- на + prepositional = location: on / at
- на + accusative = motion toward a place: onto / to
So:
- На балконе = on the balcony / at the balcony
- На балкон = onto the balcony
Here the sentence describes where the rope is, so Russian uses the prepositional case: балконе.
Russian has no articles. That means nouns like верёвка and бельё appear without anything equivalent to a, an, or the.
English has to choose based on context:
- a rope
- the rope
- a clothesline
- the laundry
In this sentence, English often says something like There is a clothesline on the balcony, and laundry is drying on it. Russian leaves that definiteness to context.
