I have heard (see  and ) that verbs can only take an indirect object if they also take a direct object. That is, all verbs which take an indirect object are ditransitive. However, consider the following sentence.
I shall provide you with what you need.
Here, the verb 'provide' is monotransitive, though it does also take a prepositional complement. Yet its direct object ('you') appears semantically to be more similar to an indirect object than to a direct one. This is also seen in other sentences (including ones without a prepositional phrase):
Stephan has already told me.
She informed us of her plan
I am well aware that the dative case can be marked by means of a prepositional phrase. For instance,
She donated £100 to charity.
He was sure he had returned her pen to her.
In these sentences, the indirect object is marked with a prepositional phrase headed by 'to'. But unlike the previous examples, where the objects all had the semantic role of goal (i.e. the actions were directed at them), the direct objects here have the semantic role of 'theme'.
Is it possible, therefore, for monotransitive verbs to take an indirect object only?
