Questions & Answers about Nie mamy pewności, kiedy on się zjawi.
Why is the word for certainty spelled pewności here instead of pewność?
Because of the negated verb nie mamy. When a verb is negated in Polish, its direct object usually switches from the Accusative case to the Genitive case. Pewność (certainty) is a feminine noun that ends in a consonant, so its Genitive form takes an -i, becoming pewności.
Could we say Nie jesteśmy pewni instead of Nie mamy pewności?
Yes, absolutely. Nie jesteśmy pewni translates to "we are not sure" and is very common. Nie mamy pewności translates literally to "we do not have certainty." Both express the exact same idea, though nie mamy pewności sounds just a tiny bit more formal.
Is zjawi się in the present or future tense?
It is in the future tense. Zjawić się (to show up / to appear) is a perfective verb. In Polish, perfective verbs focus on the completion of an action, so they cannot describe something happening right now. When you conjugate them using present tense endings, they automatically create the future tense. Therefore, on się zjawi means "he will show up."
