Speech Acts in Linguistics

Speech Acts in Linguistics In linguistics, a speech act is an utterance defined in terms of a speakers intention and the effect it has on a listener. Essentially, it is the action that the speaker hopes to provoke in his or her audience. Speech acts might be requests, warnings, promises, apologies, greetings, or any number of declarations. As you might imagine, speech acts are an important part of communication. Speech-Act Theory Speech-act theory is a subfield of pragmatics. This area of study is concerned with the ways in which words  can be used not only to present information but also to carry out actions. It is used in linguistics, philosophy, psychology, legal and literary theories, and even the development of artificial intelligence. Speech-act theory was introduced in 1975 by Oxford philosopher J.L. Austin in How to Do Things With Words  and further developed by American philosopher J.R. Searle. It considers three levels or components of utterances: locutionary acts (the making of a meaningful statement, saying something that a hearer understands), illocutionary acts (saying something with a purpose, such as to inform), and perlocutionary acts (saying something that causes someone to act). Illocutionary speech acts can also be broken down into different families, grouped together by their intent of usage. Locutionary, Illocutionary, and Perlocutionary Acts To determine which way a speech act is to be interpreted, one must first determine the type of act being performed.  Locutionary acts  are, according to Susana Nuccetelli and Gary Seays Philosophy of Language: The Central Topics, the mere act of producing some linguistic sounds or marks with a certain meaning and reference. So this is merely an umbrella term, as illocutionary and perlocutionary acts can occur simultaneously when locution of a statement happens. Illocutionary acts, then, carry a directive for the audience. It might be a promise, an order, an apology, or an expression of thanks- or merely an answer to a question, to inform the other person in the conversation. These express a certain attitude and carry with their statements a certain illocutionary force, which can be broken into families.   Perlocutionary acts, on the other hand, bring about a consequence to the audience. They have an effect on the hearer, in feelings, thoughts, or actions, for example, changing someones mind. Unlike illocutionary acts, perlocutionary acts can project a sense of fear into the audience. Take for instance the perlocutionary act of saying, I will not be your friend. Here, the impending loss of friendship is an illocutionary act, while the effect of frightening the friend into compliance is a perlocutionary act. Families of Speech Acts As mentioned, illocutionary acts can be categorized into common families of speech acts. These define the supposed intent of the speaker. Austin again uses How to Do Things With Words to argue his case for the five most common classes:   Verdictives, which present a findingExercitives, which exemplify power or influenceCommissives, which consist of promising or committing to doing somethingBehabitives, which have to do with social behaviors and attitudes like apologizing and congratulatingExpositives, which explain how our language interacts with itself David Crystal, too, argues for these categories in Dictionary of Linguistics. He lists several proposed  categories, including directives (speakers try to get their listeners to do something, e.g. begging, commanding, requesting), commissives (speakers commit themselves to a future course of action, e.g. promising, guaranteeing), expressives (speakers express their feelings, e.g. apologizing, welcoming, sympathizing), declarations (the speakers utterance brings about a new external situation, e.g. christening, marrying, resigning). It is important to note that these are not the only categories of speech acts, and they are not perfect nor exclusive. Kirsten Malmkjaer points out in Speech-Act Theory, There are many marginal cases, and many instances of overlap, and a very large body of research exists as a result of peoples efforts to arrive at more precise classifications. Still, these five commonly accepted categories do a good job of describing the breadth of human expression, at least when it comes to illocutionary acts in speech theory. Sources Austin, J.L.
