Re: Two different usages of the verb “to have” in combination with a noun and Partici
I to have + noun + Participle II implies that the action has been performed on the noun object not by the subject but from the outside (the subject is inactive).
II to have + noun + Infinitive implies causing an action, and have here is synonymous to make as a causative verb.
I'm aware that there might be other explanations -- worded in a different way.
