Etymology: The prefix "mis-" is an Old English word with a wide reach, while "diagnosis" is a Greek term that English borrowed much later. Put together, they form a word that is essentially a plain compound, not a coinage with a famous backstory. The second half traces back to the ancient Greek "diagignōskein," built from "dia-" (meaning "through" or "apart") and "gignōskein" ("to know" or "to recognize"). Its literal sense is something like "to know thoroughly" or "to discern." The Greek noun "diagnōsis" passed into Latin as "diagnōsis" and then into English as "diagnosis," carrying the sense of recognizing a condition by distinguishing it from others. "Mis-" comes from Old English, where it meant "wrongly" or "amiss," and it is the same prefix found in "mistake" and "misjudge." Joining it to "diagnosis" yields a word meaning a wrong identification of a disease or condition. The compound is a straightforward English formation, and the record does not show a specific first user, so its history is best understood as the everyday combination of two long-established parts.
