Etymology: The verb "underdiagnose" is a plain English compound: the prefix "under-", meaning too little or insufficiently, attached to "diagnose". The prefix is old, descending from Old English "under", which has long meant "below" or "beneath" and by extension "not enough." Its use in English is productive, so speakers have readily attached it to many verbs, and "underdiagnose" follows that pattern. The base word "diagnose" has a more traceable history. It comes from Ancient Greek "diagignōskein", built from "dia-", meaning "through" or "apart," and "gignōskein", meaning "to know" or "to recognise." The sense was discerning or distinguishing something by close examination. The Greek noun "diagnōsis" passed into Latin and then into English as "diagnosis," and "diagnose" was formed from that noun in English. Taken together, the word describes a failure of the discerning process: a condition is present, but the examination does not catch it often enough to match how common it actually is.
