The story
Picture a Roman official writing an instruction at the top of a document, setting out what must happen before anyone can argue with it: that was the world of Latin praescribere, “write before.” By the late fourteenth century, English prescription was mainly a legal word, describing a right acquired through long, uninterrupted possession—rather like a title deed produced by time itself. The medical sense arrived in the 1570s, when a doctor’s written directions became a kind of advance script for the patient’s treatment. The word has been confused with proscription since about 1400, even though prescription tells you what to use, while proscription tells you what to avoid or ban. Remember it as “something written beforehand”: whether it governs land, law, or a bottle of pills, a prescription tries to decide the next move before you make it.
