Questions & Answers about Я ставлю стакан на стол.
What case is стакан in, and how do you recognize it?
Стакан is in the accusative case as the direct object of the verb ставлю. For inanimate masculine nouns with a hard stem (like стол, стакан), the accusative form is identical to the nominative. You recognize it because it answers “What?” (Что?) after the verb: Я ставлю что? – стакан.
Why is стол also in the accusative case, even though there’s a preposition?
The preposition на can govern either the prepositional (location) or the accusative (direction) case. Here, because the action is placing something onto the table (motion toward a target), на takes the accusative: на стол (not на столе, which would mean “on the table” in a static sense).
What exactly does на столе mean, and how is it different?
На столе is на + prepositional case. It means “on the table” as a location (where something is).
- Я ставлю стакан на стол (accusative): I am putting the glass onto the table (movement).
- Стакан стоит на столе (prepositional): The glass is standing on the table (no movement).
Why do we use ставлю instead of поставлю?
