- Patient (grammar)
linguistics, a grammatical patient is the participant of a situation upon whom an action is carried out. A patient as differentiated from a theme must undergo a change in state. At the very least, there is debate to this effect. Also, "patient" is the name of the thematic relation with the above definition.
Typically, the situation is denoted by a sentence, the action by a
verbin the sentence, and the agent by a noun phrase.
For example, in the sentence "Jack ate the cheese", "the cheese" is the patient. In certain languages, the patient is declined for case or otherwise marked to indicate its grammatical role. In Japanese, for instance, the patient is typically affixed with |o| (the
hiraganaを). Although Modern English does not mark grammatical role, patienthood is represented irregularly in other ways; for instance, with the morphemes "-en", "-ed", or "-ee", as in "eaten", "used", or "payee".
The grammatical patient is often confused with the
direct object. However, there is a significant difference. The former is based explicitly on its relationship to the verb, whereas the latter is based primarily on its relationship to the subject. For example, in the phrase "The manbites the dog", "the dog" is both the patient and the direct object. By contrast, in the phrase "The dog is bitten by the man", "the dog" is still the patient, but now stands as the phrase's subject; while "the man" is the agent and the direct object. The term themeis often used to describe the same relation as patient.
