Communication is an integral part of human life, and speech is one of the main ways we communicate with each other. The communicative function of speech refers to the ability of language to convey meaning and facilitate social interaction between people. In this article, we will discuss the communicative function of speech and its importance for human communication. The communicative function of speech can be divided into two main categories: informative and expressive. Informative speech is used to convey factual information such as news, instructions, or descriptions. Expressive language, on the other hand, is used to express emotions, attitudes and feelings. These two functions are often intertwined, since informative speech can also be expressive, and expressive speech can convey information. The informative function of speech is critical to facilitating communication between people. Through informative speech, we can share ideas, knowledge, and experiences with other people. Informative speech can be used to convey important information, such as instructions for completing a task, details about an event or situation, or facts about a particular topic. In addition to conveying information, informative speech can also be used to establish and maintain social relationships. When we use informative speech, we often strive to find common ground with our interlocutor. By sharing information and experiences, we can establish mutual understanding and establish connections with other people. The expressive function of speech is no less important in human communication. Expressive speech allows us to communicate our emotions, attitudes and feelings to others. Through expressive speech we can convey joy, sadness, anger and a wide range of other emotions. Expressive language can be used to express our opinions, beliefs and values ​​and can be crucial in shaping our personality. In addition to expressing emotions, expressive language can also be used to establish and maintain social relationships. When we use expressive language, we often seek to connect with our interlocutor on an emotional level. By sharing our feelings and attitudes, we can generate empathy and understanding in other people, which can be critical to establishing and maintaining relationships. The communicative function of speech plays an important role in human communication. Without the ability to convey meaning and facilitate social interaction through language, our ability to communicate and form connections with others would be severely limited. Therefore, the study of speech and its communicative function is of great importance in such fields as linguistics, psychology and communication studies. In conclusion, it should be noted that the communicative function of speech plays a vital role in human communication. Through informative and expressive language, we can convey meaning, create connections, and promote social interaction between people. The ability to communicate effectively through speech is essential in both personal and professional contexts, and the study of speech and its communicative function is critical to understanding human communication and the role of language in our lives.
