Etymology: Underreporting is a compound built from the prefix "under-" and the verb "report," and its meaning follows directly from the two parts: to report something at less than its true extent. The prefix comes from Old English "under," which descends from a Proto-Germanic form that also gave German "unter" and Dutch "onder." The base verb "report" arrived through Old French "reporter" from Latin "reportare," meaning "to carry back," so a report was originally something carried back to a listener. Words built with "under-" often describe doing something too little, too low, or beneath the proper level, and "underreporting" follows that pattern. The noun form has a particular use in statistics and public health, where it names the gap between recorded cases and actual ones, such as crimes that go unlogged or illnesses that go unnoticed. The word therefore names a shortfall in the count itself, not a mistake in the report that was filed.
