Kommissive

Kommissive are a class of illocutionary acts in pragmatics in which the speaker commits to carrying out a future action. Core examples include promises, vows, offers, and threats. By making a commissive, the speaker signals an intention to act in a specified way and, often, to do so under certain conditions. The act is fundamentally about the speaker’s commitment rather than about persuading the listener to take a course of action.

Commissives are distinct from directives, which aim to elicit actions from others (such as requests or commands), and from expressives (which express attitudes or emotions) or declarations (which change the status of some entity). The defining feature of a commissive is the speaker’s commitment to a future act. The strength and credibility of the commitment depend on the speaker’s ability to fulfill it, as well as on context, timing, and any stated conditions. Committment can be explicit, as in “I will submit the report by Friday,” or implicit, as in “I’ll take care of that.” Offers and vows function as commissives too, with offers typically inviting reciprocal commitment and vows marking especially solemn commitments. Threats can also be viewed as commissives, committing the speaker to a future punitive or otherwise specified action if conditions are met.

In linguistic analysis, commissives are examined for their temporal orientation (future tense or aspect), conditionals, and how they convey obligation, intention, and reliability. They play a central role in studies of trust, cooperation, and social interaction, showing how language encodes personal commitment and future behavior in everyday and formal discourse.
