Do not look for the term 'reduced indirect object' elsewhere. I only invented it to explain the different positions of indirect objects.
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".
In both sentences, we can omit the preposition: "I give her the book" and "I bought her a book". Because in both sentences, the indirect objects are reduced to 'her', we refer to this component as the _reduced_ indirect object.
In Dutch, we can also drop the prepositions _aan_ (to) and _voor_ (for). It is, however, less common to do this with indirect objects that take the preposition _voor_.
We find the _un_ reduced indirect object somewhere in the right part of the main clause. But if we omit the preposition ( _aan_ or _voor_), the indirect object occurs in the left part of the main clause.

Jullie hebben | hun | de waarheid | verteld
You (plural) have told them the truth.
Had we not omitted the preposition _aan_, the sentence would have looked differently:

Jullie hebben | de waarheid | aan hen | verteld
You (plural) have told them the truth.
_Aan hen_ is the correct form, but _aan hun_ is more commonly used and no longer considered incorrect. See also [Them: 'hen' or 'hun'?](#/lesson/Pronouns.Ps07)
We can also omit _voor_, which is more common in Flanders than in most parts of the Netherlands.
