Conventions are established rules or practices that guide how we communicate and behave in different situations. They help create a sense of order and understanding in society. For example, in writing, conventions like grammar and punctuation ensure that our messages are clear. In social settings, conventions dictate how we greet each other, such as a handshake or a wave. In the world of theater, conventions can refer to the accepted techniques and styles used in performances. For instance, the use of stage directions helps actors know where to move and how to interact with each other. These conventions make it easier for audiences to follow the story and enjoy the experience.
