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.
