why is it " mi dankas vin", but " Mi fidas al vi". Why does one require the preposition "al" and the other makes use of the accusative? is one verb transitive and the other not? Mi ne komprenas
The object of a preposition is an indirect object. The accusative marks the direct object.
I give the ball to you.
"ball" is the direct object of "give". It's what's given.
"you" is the indirect object of "give". It's the recipient of the given thing (the ball).
So it's the difference between "I thank you" and "I give my thanks to you".
I have a question. Say I want to extend this sentence to: "I thank you for waiting for me". Is the accusative ending on both vin and min? Eg: "Mi dankas vin por attendi min."?
