If you land a role in a local play, you will probably have to memorize several lines of dialogue. If you disagree with how that play is being produced, you may want to open up a dialogue with the director.
Dialogue can refer to spoken lines in a dramatic performance such as a play, a film, or a television show. It is also any conversation between two or more people. On the written page, dialogue between characters is usually enclosed by quotation marks. When persons representing different political parties or different nations are said to engage in a dialogue, it means they are probably negotiating something of importance.
