Questions & Answers about Dziewczyna była pewna, ale oni nic nie wiedzieli.
Why is it wiedzieli and not wiedziali?
The verb wiedzieć (to know) has an irregular past tense where the stem vowel changes. For most forms, it uses an -a- (like on wiedział, ona wiedziała, one wiedziały). But for the masculine personal "they" form (oni), the -a- changes to an -e-, making it wiedzieli.
Why does the sentence use both nic and nie?
Polish requires a double negative. If you use a negative word like nic (nothing), you must also make the verb negative with nie. Literally, this sentence translates to "they didn't know nothing".
Why is it pewna instead of the dictionary form pewny?
The adjective meaning "sure" or "certain" has to match the noun it describes. Since dziewczyna (girl) is a feminine noun, the adjective takes the feminine ending -a, becoming pewna.
Do we have to include the pronoun oni here?
