imp

Imp is a term with several distinct meanings in folklore, culture, and technology.

In folklore and popular culture, an imp refers to a small, mischievous supernatural being. Imps are typically portrayed as lesser in power than full-fledged demons and are often tricksters who cause trouble or tempt humans. The concept appears in various European traditions and has extended into modern fantasy literature, film, and games, where imps are commonly depicted as either troublesome helpers or minor antagonists. The term also serves as a general descriptor for someone who behaves in a playful, impish, or slyly mischievous way.

Etymology and usage: The word imp dates to Middle English and has appeared in multiple European languages with related senses. The precise linguistic origin is uncertain, but by the late medieval period the term was established to describe a small demonic or sprite-like being. Over time, the sense broadened to include mischievous human behavior, yielding phrases such as “impish” to characterize playful naughtiness in people, especially children or clever tricksters.

In technology: IMP is an acronym used in early computer networking for Interface Message Processor, a device that connected host computers to the ARPANET in the 1960s and 1970s. IMPs were foundational to the development of packet-switching networks and, indirectly, to the modern Internet, though they are obsolete today.

In games and media, imps frequently appear as small demon-like creatures or minions, notably in certain role-playing and action games. They serve as approachable early-stage adversaries or companions, depending on the title.
