Questions & Answers about Detektyw widzi coś na stole.
Why doesn't the word coś change its ending in this sentence?
The verb widzi (sees) requires its direct object to be in the Accusative case. The word coś (something) is the object here, but luckily for learners, its Accusative form is exactly the same as its basic dictionary form!
What if the detective sees "someone" instead of "something"? Would the word change then?
Yes! If the detective sees "someone" (ktoś), the word has to change to fit the Accusative case. The sentence would become Detektyw widzi kogoś na stole (The detective sees someone on the table).
Why is the word for table spelled stole here instead of stół?
The preposition na (on) requires the Locative case when talking about a fixed position. The dictionary word is stół. When we add the Locative ending -e, two changes happen inside the word: the ł softens to l, and the vowel ó shifts back to o. That gives us stole.
How do we know widzi means "he sees" and not "I see" or "you see"?
Widzi is the third-person singular form of the verb widzieć (to see), matching the subject detektyw (the detective). If it were "I see", it would be widzę, and "you see" would be widzisz.
