6.8 Commissive Speech Function

Commissive Speech Function involves utterances in which the speaker commits to a certain course of action in the future. This type of speech act expresses the speaker’s intention or promise to do something, thereby binding the speaker to perform the stated action. Unlike assertives, which convey information or beliefs, commissives focus on the speaker’s future behavior, establishing a form of obligation or commitment through language.

Nature and Characteristics of Commissive Speech Function

Definition and Scope

Commissive speech acts are a category within speech act theory that primarily deal with the speaker’s commitment to an action. These acts are performative in that the act of saying them enacts a promise, vow, or undertaking, rather than merely describing a situation or conveying information. The speaker positions themselves as an agent responsible for carrying out the action they declare.

Key Features

• Future-oriented: Commissives always relate to future intentions or actions.
• Speaker-bound: The commitment is explicitly or implicitly made by the speaker.
• Binding: They create a social or moral obligation for the speaker to fulfill the promise.
• Performative nature: The utterance itself enacts the commitment.

Types of Commissive Speech Acts

Promises

Promises are explicit commitments by the speaker to perform a specific action in the future. They often include conditions or circumstances but express a clear intention to fulfill the stated action.

Offers

Offers propose a future course of action, usually extending an option to another participant. While the speaker commits to the possibility of acting, the acceptance of the offer by the listener is often required before the commitment is fully binding.

Vows and Oaths

Vows and oaths are solemn or formal commitments that often carry cultural, religious, or legal weight. They emphasize the sincerity and seriousness of the speaker’s future commitment.

Threats (as a special case)

Threats can also be considered commissive acts where the speaker commits to performing a harmful or undesirable action if certain conditions are met. Though negative in tone, they are still binding commitments about future behavior.

Functions and Effects in Communication

Establishing Trust and Reliability

By making commitments, speakers signal reliability and intention to act, which can build trust in interpersonal, professional, or social contexts.

Facilitating Cooperation and Planning

Commissive speech acts enable coordination by clarifying who will do what and when, thus structuring cooperative activities and expectations.

Regulating Social Behavior

Promises, vows, and oaths function as social contracts that regulate behavior and establish accountability, often reinforced by social norms or legal systems.

Contextual and Pragmatic Considerations

Conditions for Successful Commissive Acts

• Sincerity: The speaker must genuinely intend to fulfill the commitment.
• Capability: The speaker should be able to perform the promised action.
• Appropriateness: The context must allow the speech act to be recognized as a genuine commitment.

Possible Misuses and Failures

• Breaking Promises: Failure to act as committed can lead to loss of credibility.
• Insincere Commissives: Utterances without genuine intention may be perceived as deceptive or manipulative.
• Ambiguity: Vague or conditional commissives can cause misunderstandings.
