Questions & Answers about Moja siostra nie lubi zmywać naczyń.
Why is it moja and not moją?
Because siostra is the subject of the sentence and stands in the nominative case, so the possessive must also be nominative feminine singular: moja. The form moją is accusative/instrumental and would be used if “my sister” were an object, e.g. Widzę moją siostrę (I see my sister).
Why is it lubi and not lubię?
The verb lubić must agree with the subject. Moja siostra = she = 3rd person singular, so you use lubi. Present-tense forms:
- ja: lubię
- ty: lubisz
- on/ona/ono: lubi
- my: lubimy
- wy: lubicie
- oni/one: lubią
Why is nie written separately (nie lubi) and not as one word?
With verbs, nie is written separately: nie lubi, nie wiem, nie robi. With many adjectives and nouns it’s written together (spelled as one word), e.g. nieszczęśliwy (unhappy), nieprawda (untruth). So here, as a verb, it’s correctly separate.
Why zmywać and not myć? Are both correct?
