In a jiffy

Origin

The intriguing word 'jiffy' sprang into the English lexicon in the late 18th century, a linguistic bolt of lightning designed to capture the essence of extreme brevity. While its exact parentage remains shrouded in a delightful mystery, some linguists point to its potential birth in British slang, a playful coinage to denote the shortest imaginable sliver of time. Others whisper of a connection to early electrical science, where "jiffy" informally became the benchmark for the merest instant of an electrical discharge. Whatever its true cradle, the phrase quickly electrified common speech, becoming the perfect, snappy shorthand for doing something with breathtaking speed, making it clear that a moment's delay is simply out of the question.
