Questions & Answers about Żeby wykluczyć to wątpliwe przypuszczenie, musimy znaleźć dowód.
The lesson is about the conjunction skoro (since). Why do we use żeby at the start of this sentence?
While skoro introduces a logical deduction based on an existing fact (since X is true, Y happens), żeby combined with an infinitive expresses a purpose or goal. Here, ruling out the assumption is the goal, and finding proof is the required action to achieve it.
I usually hear dowód used to mean an ID card. Is it the exact same word here?
Yes! The word dowód fundamentally means proof or evidence. The everyday term for an ID card is dowód osobisty, which literally translates to personal proof of identity. In an investigative context like this, it just means proof.
The phrase to wątpliwe przypuszczenie is the direct object of the verb wykluczyć. Why didn't its endings change?
The verb wykluczyć requires the accusative case. Because przypuszczenie is a neuter noun, its accusative form is exactly the same as its nominative form. As a result, the pronoun to, the adjective wątpliwe, and the noun remain in their dictionary forms.
Could I use aby instead of żeby in this sentence?
