Etymology: "Underbounding" is the present participle and gerund of "underbound," which is formed from the prefix "under-" and "bound." The base word "bound" is the one that matters most here: it descends from Old English "bunden," the past participle of "binden," meaning "to tie or fasten." In its mathematical and computing sense, "bound" came to mean a limit that a quantity cannot pass, so a lower bound is the smallest value something may take, and an upper bound is the largest. The prefix "under-" adds the sense of falling beneath or below. Putting the two together gives the idea of setting a limit from below, which is exactly what the term describes: a constraint that fixes the minimum extent or value a variable or parameter may have. The formation is transparent, so the word reads almost like a literal description of its own meaning.
