A comparison that uses “like” or “as” is a simile. “My love is like a red, red rose” and “he fought like a lion” are familiar examples. The explicit marker makes the comparison clearer and often gentler than a metaphor, which asserts identity rather than resemblance.

Similes appear constantly in everyday speech as well as in literature. They help explain the unfamiliar by reference to the familiar, or they add vividness by linking two domains. A well-chosen simile can make an abstract quality suddenly concrete or an ordinary action suddenly memorable. Overused or predictable similes, however, lose their force and become clichés.

Writers learn to craft similes that feel fresh and precise. The best ones illuminate both sides of the comparison: the subject is seen more clearly, and the vehicle is also enriched by the unexpected association. Recognizing similes is straightforward; using them with originality is a lifelong craft.
