Questions & Answers about Eikö meillä ole valtuutusta toimia johtajan puolesta?
Why does johtaja become johtajan before puolesta?
The word puolesta is a postposition meaning "on behalf of" or "for." Like most Finnish postpositions, it requires the noun it belongs to to be in the genitive case. That is why johtaja (manager) takes the -n ending to become johtajan.
Could I use sijasta instead of puolesta here?
Grammatically yes, because sijasta also requires the genitive case. However, it changes the meaning. Johtajan puolesta means you are acting "on behalf of" the manager as their representative. Johtajan sijasta would mean you are acting "instead of" the manager, implying you are replacing them.
Why do we use eikö meillä ole rather than a form of emmekö for "don't we have"?
Finnish uses the "on someone" (adessive case) + "is" (olla) structure for possession. In a negative question, the negative verb ei takes the question clitic -kö in the third-person singular (eikö), regardless of who the possessor is. It is literally asking "Is it not on us...?" so the verb doesn't conjugate to match "we" (emmekö).
Why is valtuutus (authorization) in the partitive case (valtuutusta)?
