Questions & Answers about Oferujemy wam dobrą pracę.
Why is wam used here instead of wy or was?
wam is the Dative case of the plural pronoun wy (you all). The verb oferować (to offer) requires the Dative case for the person receiving the offer, because you are offering something to them.
Does wam have a longer, emphatic form for when I want to stress it?
No, plural Dative pronouns like nam (to us) and wam (to you all) only have one form. Unlike singular pronouns that have short and long forms (like ci and tobie for 'to you'), you just use wam whether you are emphasizing it or not.
Could I change the word order and say Wam oferujemy dobrą pracę?
Yes, but it changes the focus. Polish word order is flexible, so putting wam at the very beginning emphasizes who is getting the offer. It sounds like 'To you we are offering a good job' (perhaps implying we are not offering it to someone else). The current word order is the most neutral.
Why does the ending of dobra praca change to dobrą pracę here?
