Etymology: "Underruns" is the third-person singular present form of "underrun," a verb meaning to run under something. The verb is a plain compound: "under-" joined to "run," with the prefix descending from Old English "under," which traces back through Proto-Germanic to the same ancient root that gives German "unter." English has long used "under-" as a productive prefix, and "underrun" follows that pattern, combining the sense of position below with the basic action of running.

Synonyms: runs under, exceeds
