The results of the study showed that 227 expressive utterances were found from six videos analyzed. These utterances were classified into four forms of expressive speech acts, namely direct literal speech acts, direct non-literal speech acts, indirect literal speech acts, and indirect non-literal speech acts. In addition, nine functions of expressive speech acts were identified, namely expressing gratitude, congratulating, apologizing, expressing condolences, welcoming, praising, criticizing, complaining, and greeting.
