Sim

Part of speech: noun

Definitions

1. A unit that represents a single instance of a function, often used in gaming and technology contexts
2. An abbreviated form commonly utilized in discussions about simulations or simplifications
3. A term that may refer to a device that enables mobile services without a physical card, often called a SIM card

Etymology: The three letters in SIM stand for nothing grand: the abbreviation is a clipping of "simulator," a word that began as a term for something that imitates reality. The chip itself was built to imitate a subscriber's identity, so the shortened name fits the device's function. Its ancestry runs through "simulate," which comes from Latin "simulare," meaning "to make like" or "to copy," and the agent suffix "-or" (a Latin "-tor" that passed through Old French and Middle English) turns that action into a thing that performs it. The word "simulator" therefore names an agent that carries out simulation, and the clipped form "sim" keeps that imitative sense in a much smaller package. Its origin is a plain suffixed formation rather than a coinage with a famous author.

Synonyms: simulation, model, emulation, replica, mockup
