An object of the verb can be.an
indirect object. This is the second object TO or FOR which the action
of the verb is directed. The indirect object precedes
the direct object.
Please give that man some money.
indirect object may also be expressed in a TO or FOR phrase after
the direct object:
Please give some money to that man.
says on page 191:
Although grammarians often classify the TO phrases
after certain verbs as indirect objects, these phrases could
with equal justification
be called merely prepositional
This probably doesn't help much! Nomenclature is not
always consistent, and it's confusing.
