Etymology: "Unlevels" is the third-person singular present form of the verb "unlevel," which means to make a surface uneven. The verb is formed from the prefix "un-," meaning "not" or "reverse of," attached to "level," so it literally reverses the act of levelling a surface. Its "level" element traces back to the Latin "libella," a small balance or spirit level, which passed into Old French and then English as a word for a flat, even plane.
