looper

A "looper" is a word that shows up in a few different worlds, but it usually points back to repetition or movement in a loop. In music, it can mean a performer or a device used to record and repeat short parts, building layers of sound live. On a golf course, it is a casual word for a caddie, from the loop around the course. In nature, some caterpillars are called "loopers" because they move by pulling their bodies into a loop and stretching forward again. The word can also appear in film and pop culture, but most of the time it suggests something or someone tied to looping action.

The word "looper" has grown from a practical term into one with several clear meanings, all linked in some way to repetition, circling, or working in loops. In film and sound production, a "looper" can mean an actor who records extra dialogue or background voices for scenes, a use that comes from the older practice of replaying short film sections in a loop so the timing could match the screen action.

Beyond the studio, the term takes on several distinct identities. In music, a "looper" may be a person who performs with looping technology or the device itself, especially one that records and repeats short vocal or instrumental phrases in real time. In sport, especially golf, "looper" is a familiar slang term for a caddie, taken from the loop made around the course during a round.

The term also has a place in nature; "looper" refers to the larvae of certain moths, such as the cabbage looper, which move in a looping arch because they do not have the full set of middle legs that many caterpillars have. In popular culture, the word also became widely known through the 2012 science fiction film Looper, in which it refers to a killer working inside a time-travel system. From a recording booth to a golf course to a garden leaf, a "looper" is usually something or someone defined by repeated motion, repeated sound, or a path that circles back on itself.
