The word "underrun" has its roots in Middle English, deriving from the combination of two words: "under" and "run".

The word "under" originates from Old English "under" which signifies "beneath" or "below". It has Indo-European roots and can be traced back to the Proto-Germanic language.

The word "run" comes from Old English "rinnan" which means "to flow" or "to move quickly". It has similar Indo-European origins and can be traced back to the Proto-Germanic language as well.

The combination of "under" and "run" gives rise to "underrun" which originally referred to the act of flowing or running beneath or below something. Over time, its usage expanded to include various contexts, such as military tactics, computer networking, or even the issue of printed material exceeding its allocated space.
