Questions & Answers about Ona zawsze marzy o tym, żeby kupić jacht.
Why do we need o tym here instead of just saying Ona zawsze marzy, żeby...?
In Polish, the verb marzyć (to dream) pairs with the preposition o (about). You cannot attach o directly to a connecting word like żeby. Instead, Polish uses a "dummy" pronoun to (this/it). So, you literally say "she dreams about this, that..." (marzy o tym, żeby...).
Why is the word for "this" spelled tym?
The preposition o (when meaning "about") requires the following noun or pronoun to be in the Locative case. The Locative form of the pronoun to (this/it) is tym.
How does żeby relate to the conditional mood we are learning?
The word żeby is a combination of że (that) and the conditional particle by. It is used to express hypothetical situations, goals, or desires. While English simply says "dreams of buying", Polish frames it hypothetically: "dreams about this, that she would buy".
Why is kupić in the infinitive here, instead of a conditional verb form like kupiłaby?
Because the person dreaming and the person buying the yacht are the same. When the subject is the same for both actions, Polish uses żeby + the infinitive (kupić). If she dreamed that someone else would buy a yacht, you would use a conjugated conditional verb, like żeby on kupił (that he would buy).
