Unlike idioms tied to a trade, fable, or historical event, this phrase is a transparent, compositional expression built directly from ordinary words — “time” treated as a resource that can be “lost” like money or property, and then “made up,” a verb pattern also used for compensating a shortfall (as in “make up a deficit”). This way of speaking about time as a quantifiable, losable resource became especially natural in English once clock-based, scheduled daily life took hold from the early modern period onward, but the phrase itself doesn’t trace to any single identifiable source; it belongs to a broad, ordinary vocabulary of time-management language that developed gradually rather than being coined at one particular moment.
