Etymology: "Fatigueable" is an alternative spelling of "fatigable," which came into English by way of French. The French "fatigable" descends from the Latin "fatīgābilis," meaning capable of being wearied or tired, built on "fatīgāre," to tire out or weary. Those two Latin parts, the verb stem and the suffix meaning "able to be," were joined to give a plain sense of "able to be worn down." The spelling with "ue" follows the pattern of "fatigue," which entered English from French and had earlier been related to the same Latin verb. Because English already had the noun "fatigue" with its silent-looking final "ue," writers sometimes extended that spelling to the adjective, producing "fatigueable" beside the more regular "fatigable."
