Questions & Answers about Mi dankas vin pro la sincera respondo; vi ĉiam estas sincera kun mi.

Why is it vin and not vi after dankas?

Because danki is a transitive verb: it takes a direct object. In Esperanto, direct objects usually get the -n ending.

• mi = I
• vi = you
• vin = you, as the object

So:

• Mi dankas vin = I thank you

This is different from English, where we do not mark the object with an ending.

Why doesn’t Esperanto use a preposition in Mi dankas vin?

Because danki normally works directly with an object in Esperanto. You simply thank someone:

• Mi dankas vin = I thank you

You do not need a word like to here. A native English speaker may expect something like I give thanks to you, but Esperanto uses the simpler direct-object pattern.

Why is pro used in pro la sincera respondo?

Pro means because of, on account of, or for in the sense of the reason.

So:

• Mi dankas vin pro la sincera respondo = I thank you because of / for the sincere answer

This is a very common pattern:

• Mi pardonpetas pro la eraro = I apologize for the mistake
