Questions & Answers about На столе лежит серебряное кольцо.
Because на can take different cases depending on the meaning:
- на стол = onto the table → motion toward a surface, so Russian uses the accusative
- на столе = on the table → location, so Russian uses the prepositional
In this sentence, the ring is already located there, so Russian uses на столе.
Compare:
- Я кладу кольцо на стол. = I put the ring onto the table.
- Кольцо лежит на столе. = The ring is lying on the table.
Столе is the prepositional singular of стол.
The basic form is:
- стол = table
After на when it means location, you usually use the prepositional case:
- на столе = on the table
- на полу = on the floor
- на полке = on the shelf
So столе is simply the form of стол required after на in a location meaning.
