Etymology: "Underdefends" is the third-person singular present form of "underdefend," a verb meaning to give weak or insufficient protection. Its root is the verb "defend," which came into English from Old French "defendre," itself from Latin "defendere," meaning to ward off or protect. The prefix "under-" is the familiar English element meaning "below" or "insufficiently," as in "undercook" or "underestimate." Attaching it to "defend" produces a word whose sense is the reverse of a full defence: a team, a border, or a person that underdefends is guarding, but not enough. Because the prefix is productive, speakers can form such verbs freely, which is why "underdefend" reads as a transparent compound rather than an old coinage.
