Questions & Answers about Dobry mechanik zachęca mnie do pracy nad tym silnikiem.
Why does the sentence use do pracy instead of the infinitive pracować (to work)?
In English, we say "encourage someone to do something" using a verb. In Polish, the verb zachęcać (to encourage) requires the preposition do followed by a noun in the Genitive case to show what you are being encouraged towards. So, you are literally being encouraged "towards work" (do pracy).
Doesn't the preposition nad normally mean "above" or "over"? Why does it mean "on" here?
Literally, yes, nad means "above" or "over." However, in Polish, when you talk about working on a project, an object, or a problem, you use the fixed phrase praca nad (work on) or pracować nad (to work on). This combination always requires the noun to be in the Instrumental case.
Why is the pronoun mnie used here instead of mi?
The verb zachęcać takes the Accusative case for the person being encouraged (the direct object). Mnie is the Accusative form of ja (I). Mi is the Dative form (used for indirect objects like "to me" or "for me"), which doesn't fit the requirements of this verb.
