摘要:In English, studies on various forms and functions of speech acts have been carried out by some previous researchers. However, specific studies on impositive speech acts are still limited. The purpose of this research was to find out the forms and functions of impositive speech acts that exist in the forms and functions of the directive, assertive, expressive, commissive, and declarative speech act in the novel Assassin's Creed: Renaissance. The researcher used three main theories as indicators of impositive speech acts, namely cost-benefit (Leech), face-threatening act (Levinson), and verb (Lee). To analyse the data, the researcher was assisted by three raters to analyse the impositive speech acts through a focus group discussion. Furthermore, all data will be analyzed through four stages, namely domain analysis, taxonomy, componential, and cultural theme analysis. The results showed that the use of speech acts in directive form was the most widely used. At last, the function of the impositive speech act was to command.
