The term "theme" refers to a central idea or concept that is explored or developed in a literary work, such as a novel, play, or poem. It is the underlying message or moral that the author wants to convey to the reader. Themes can be broad and universal, touching on topics like love, friendship, or the human condition, or they can be more specific and focused on social issues, historical events, or personal struggles. Themes are often expressed through the actions, dialogue, and symbolism within a work of literature, and they can provide insight into the deeper meaning and purpose of the text.
