"Indefatigable" traces back to the Latin verb "fatigare." Which word in the list below do you think also descends from "fatigare"?

Tired of guessing? Answer B, "fatigue," meaning "to cause to become very tired," has the Latin verb "fatigare" at its root. "Indefatigable" came into English in the early 1600s, and it traces via Middle French to Latin "indefatigabilis" -- a combination of two prefixes ("in-" and "de-") and the verb "fatigare," meaning "to fatigue." Not long after, "fatigue" made its way into English from the French verb "fatiguer," meaning "to fatigue," also a descendant of "fatigare." Although both words have "fatig" in them, they aren't pronounced the same: "indefatigable" has the stress on "FAT," whereas "fatigue" has the stress on the "TEEG," as in \fa-TEEG\.
