Cash and Cache

Cache and cash are homophones (words that are pronounced alike but have different meanings, origins, or spelling) whose likeness in sound may lead to perplexity.

Cache primarily refers to a thing that is hidden or stored somewhere, or to the place where it is hidden. It has recently taken on another common meaning, “short-term computer memory where information is stored for easy retrieval.” Cash, on the other hand, is most often used in the sense “ready money.”

If you find yourself confused by these words, remember that you can store cash in a cache, but you can't do the reverse. Be mindful, too, that if you run out of cash you won't be able to buy something, but if you're short on cache, your computer won’t work.

Word History

Etymology

Noun

borrowed from North American French, from French, "hiding place," noun derivative of cacher "to hide, conceal," going back to Old French cachier, quaichier "to put away, lock up, cover, remove from view, conceal" (also Middle French cacher "to press, crush"), going back to Vulgar Latin *coācticāre "to press, constrict," from Latin coāctāre "to compel" (frequentative of cōgere "to drive together, collect, compress, compel") + -icāre, verb formative — more at cogent

Note: The etymological sense "to compress, constrict" is not attested for the Old French verb, though it likely existed and is apparent in the prefixed form escachier "to crush and flatten, break by pressing or falling on." From the sense "compress" presumably developed the senses "lock up, cover, put away," and hence "remove from view, conceal," common from the sixteenth century. The sense "to press, crush" is marginally evident in Middle French in areas in contact with Occitan, though it penetrated widely enough to form the basis for the derivative cachet "seal" (see cachet).
