"Showing vs. telling" is a writing technique that distinguishes between two ways of conveying information. "Telling" provides straightforward information, such as stating that a character is sad. For example, saying, "She felt sad" directly informs the reader of the emotion. In contrast, "showing" allows readers to infer emotions through actions, dialogue, and sensory details. Instead of saying, "She felt sad," a writer might describe her slumped shoulders, tear-filled eyes, and the way she stares blankly at the ground. This approach engages readers more deeply, allowing them to experience the character's feelings through vivid imagery and context.
