5 Directives A directive is a speech act, where the speaker requests the hearer to carry out some action - Please bring me the salt

6 Commissives A commissive is a speech act, whose purpose is to commit the speaker to carry out some action - I promise to clean the floor

7 Declaratives A declarative is a speech act, where the speaker brings about some state of affairs - I hereby pronounce you husband and wife
