Etymology: This adjective is formed by combining a straightforward negative prefix with a root word and an adjectival suffix, creating a term that describes a lack of truthfulness. The prefix "un-" is a common English element used to negate the meaning of the base word it attaches to, signaling "not" or the opposite of the root concept. The root word, "truth," comes from Old English "trēowth," which originally meant faith, fidelity, or loyalty, and then came to signify the quality of being true or in accordance with fact. This Old English term is related to "true," which traces back to the Proto-Germanic "*treuwaz," implying faithfulness or trustworthiness. Adding "-ful," an English suffix meaning "full of," to "truth" created "truthful," denoting someone or something full of truth or honesty. Then, by applying the negating "un-" at the beginning, the adjective changes to express the opposite: not full of truth, or lacking honesty. Such formations appeared in English by the late Middle Ages, as speakers expanded their descriptive vocabulary by combining known elements in productive ways. "Untruthful" thus reflects a clear and logical morphological process rather than a complex borrowing or semantic shift, neatly packaging negation and quality into a single word.
