Questions & Answers about Oszczędź mi szczegółów i stresu.
Why are szczegółów and stresu in the Genitive case instead of the Accusative?
In English, 'details' and 'stress' are direct objects, but Polish treats oszczędzić (to spare/save) as a verb of withholding or denying. Verbs that mean giving, denying, or withholding something from someone take the Dative for the person (mi) and the Genitive for the thing being withheld (szczegółów, stresu).
Could I use the long-form pronoun mnie instead of mi here?
You would only use mnie if you wanted to emphasize who is being spared, as in 'Spare me (not him) the details.' Without that contrast, the unstressed short form mi is the natural choice and usually tucks in directly after the verb.
Both szczegółów and stresu are masculine nouns in the Genitive. Why do they have different endings (-ów vs -u)?
They are in different numbers. Szczegółów is the Genitive plural (the details), which typically takes -ów for masculine nouns. Stresu is the Genitive singular (the stress), which takes -u, a common ending for masculine inanimate abstract nouns.
