What is a simile?

A simile is indeed a comparison that utilizes the words "like" or "as" to draw parallels between two different things. This literary device serves to create vivid imagery and make descriptions more relatable or expressive. For example, saying "her smile was like sunshine" helps the reader understand the warmth and brightness of her smile by comparing it to something familiar and universally acknowledged.

The use of "like" or "as" is crucial in distinguishing similes from other forms of comparison. In contrast, metaphors, another literary device, make direct comparisons without these linking words. This fundamental difference highlights why the correct answer emphasizes the use of "like" or "as" in a simile. The ability to convey complex ideas or evoke strong imagery through comparisons plays a significant role in effective writing and communication.
