What is an example of a simile?

A simile is a rhetorical device used to compare two things (typically using the words “like,” “as,” or “than”).

Many common expressions are similes, including: “as quiet as a mouse,” “as strong as an ox,” and “as fit as a fiddle.”

Similes are commonly used in literature, advertising, and everyday speech. However, they should be avoided in formal contexts like academic writing.
