Prepositional pronoun
（重定向自Prepositional object）
A prepositional pronoun is a special form of a personal pronoun that is used as the object of a preposition.
English does not have distinct prepositional forms of pronouns. The same set of object pronouns are used after verbs and prepositions (e.g. watch him, look at him). In some other languages, a special set of pronouns is required in prepositional contexts (although the individual pronouns in this set may also be found in other contexts).
