Questions & Answers about На столе лежит кусочек сыра.
Why is it на столе, not на стол?
Because на can mean either onto or on, depending on the case.
- на стол = onto the table → motion toward a surface, so it takes the accusative
- на столе = on the table → location, so it takes the prepositional
In this sentence, the cheese is already located there, not moving there, so Russian uses на столе.
Why does стол become столе?
That is the prepositional case singular form of стол.
- dictionary form: стол
- prepositional singular: на столе
Many masculine nouns add -е in the prepositional singular after a preposition of location like на or в.
So:
- стол = table
- на столе = on the table
