The term "faulty" appears to have been used in literature as a versatile adjective, applied to both tangible objects and abstract ideas. In technical and physical contexts, it describes malfunctioning devices or imperfect constructions—as when Ukers denounces the inefficiency of a coffee-making device ([1]), or when Jules Verne criticizes a navigational maneuver in an underwater tunnel ([2]). Meanwhile, authors extend the term to intellectual and moral realms: Stendhal warns against faulty reasoning in matters of friendship ([3]), Jane Austen contrasts faulty character traits with virtue ([4], [5]), and Aristotle considers actions disgraceful when born of a faulty character ([6]). The word also is employed to critique errors in language and organization, whether in punctuation ([7]), historical legal texts ([8], [9]), or the even-handed arrangement of operations in military strategy ([10], [11]). Thus, across decades and genres—from the technical manuals and philosophical treatises to novels exploring human nature—"faulty" serves to highlight deficiencies, inaccuracies, or moral lapses, anchoring its meaning in both physical imperfection and abstract error.
