Questions & Answers about Rozmawialiśmy o tym, jakie przeciążenie ma ten spadek.
Why do we need o tym? Can't I just say Rozmawialiśmy o jakie...?
No, because in Polish, a preposition like o cannot directly attach to a question word like jakie to start a new clause. Instead, you use a placeholder pronoun. You take to and decline it for the case the preposition requires—here, the locative, giving us o tym (about this). Then you add a comma and start the indirect question with jakie.
Why is the question word jakie instead of jak or co?
Jakie translates here to 'what' but specifically works like an adjective meaning 'what kind of' or 'which'. Because it describes the noun przeciążenie, it has to agree with it in gender and case (neuter accusative). Jak means 'how', and co means 'what' as a standalone noun, neither of which can be directly attached to przeciążenie.
The word order is jakie przeciążenie ma ten spadek. Can I say jakie przeciążenie ten spadek ma?
You can, but it sounds slightly clunky. Polish prefers to avoid leaving the verb dangling at the very end of a subordinate clause if it can be helped. Inverting the verb and subject to ma ten spadek sounds much more natural and flows better.
Does przeciążenie literally mean 'G-force'?
