13.6.16 exercise 16: preposition to be used by adding an infinitive
In most cases an infinitive is connected to a verb with the preposition di, seldom with the preposition a and very seldom with da. Except da the prepositions to use are arbitrary, have no semantice value. The preposition da converts the infinitive in a passive infinitive and adds the meaning of obligation.
