What defines a simile?

A simile is defined as a comparison between two different things that uses the words "like" or "as" to highlight their similarities. This figure of speech creates vivid imagery and helps readers or listeners understand a concept by relating it to something they may already know. For example, saying "Her smile was like the sun" allows the reader to envision the brightness and warmth associated with the sun, making the description more engaging.

The other options describe different literary devices that do not align with the definition of a simile. Personification involves attributing human characteristics to non-human objects, exaggeration describes hyperbole, and a direct comparison without "like" or "as" refers to a metaphor. Each of these serves different functions in language and literature, but only similes specifically utilize "like" or "as" in their comparisons.
