We already discussed the indirect object in the section about the reduced indirect object. But to refresh your memory: The indirect object is the recipient of the direct object. In English, this object is preceded by either 'to' or 'for'. E.g. "I give the book to her" and "I bought a book for her".
The prepositions 'to' and 'for' can be omitted but then we are dealing with a reduced direct object, which appears in the left part.
A few common verbs that can be connected to an indirect object:
||to promise to
||to buy for
||to pay to
||to cook for
||to give to
||to make for
||to tell to
||to bring along for
|Het bedrijf zal
||een groot bedrag
||aan een liefdadigheidsinstelling
|The company will donate a large sum to a charity organisation.
Besides aan, an indirect object can also take the preposition voor:
|The chef (cook) had prepared a delicious meal for us.
