śpię
"I sleep."
The word "śpię" is used in the present tense, first-person form, indicating the action of sleeping currently and specifying where the person is sleeping.
Śpię w swoim pokoju.
I sleep in my room.
Here, "śpię" is modified by negation ("nie"), showing absence of the action of sleeping and explaining the reason.
