In Old English, the psychological verbs were semantically classified based on the semantics of action and state rather than the transitivity. When an argument was coded by the case inflection, impersonal constructions with psychological verbs had the argument of a human experiencer and a theme. They were coded by different case markers such as nominative, accusative and dative. Each of the case marked argument represented a distinct semantic function. In Middle and Modern English, the Old English impersonal psych-constructions disappeared. It was due to the loss of case endings and the use of the subject-verb order. Now we came to have grammatical relations such as subject and object for describing Modern English.
