Concept:Drama is a genre of literature written to be performed on stage, and its most defining characteristic is the use of dialogue.
Explanation:In drama, the story is told almost entirely through the words spoken by the characters.
Unlike prose fiction or poetry, a play does not rely on a narrator to describe events or feelings.
Instead, dialogue carries the action forward and reveals the personality, emotions, and intentions of each character.
It is through dialogue that conflicts arise, relationships develop, and the plot unfolds naturally.
Although setting, plot, and epilogue all contribute to a play, these features are also present in other literary forms.
Dialogue alone stands as the unique and essential element that separates drama from every other type of literature.
