Language serves various functions, but four key functions are:
1. Communicative Function: Language enables individuals to exchange information, express thoughts, ideas, and emotions, and convey messages effectively.
2. Expressive Function: It allows individuals to express their feelings, emotions, and personal identity, often reflecting attitudes or moods.
3. Directive Function: Language is used to influence others, give commands, make requests, or persuade people to take specific actions.
4. Referential Function: This involves using language to describe the world, convey facts, and provide information about objects, events, or concepts.
These functions collectively highlight the versatility and importance of language in human interaction.
