simile

Use the noun simile when describing a comparison between two fundamentally different things, such as: "His voice was smooth, like butter in a warm pan."

A simile (pronounced SIM-uh-lee) is a comparison that usually uses the words "like" or "as": "Me without a mic is like a beat without a snare," rapped Lauryn Hill in the song "How Many Mics." The word comes from similus, a Latin word meaning "the same." A simile is different from a metaphor, in which the comparison is less explicit, as in Shakespeare's line "All the world's a stage."
