Explain the difference between a simile and a metaphor.

A simile uses "like" or "as" to draw a comparison between two different things, highlighting a shared characteristic in a way that is explicit and direct. For example, saying "Her smile was like sunshine" indicates a comparison that helps to create a vivid image in the reader's mind. On the other hand, a metaphor asserts that one thing is another, implying a deeper equivalence without using "like" or "as." For instance, saying "Time is a thief" suggests that time steals moments from our lives in a figurative sense.

This distinction is important in literary and rhetorical contexts, as it informs the reader about the nature of the relationship between the compared elements. Understanding this difference enhances comprehension of language and expression, allowing for more impactful writing and communication.
