What does disingenuous mean?
Disingenuous is an adjective describing someone who is not sincere or candid, especially when they pretend to be less informed, less involved, or less calculating than they really are. A person who claims ignorance of something they clearly know about, or who offers praise they plainly do not mean, can be called disingenuous. The word implies a subtle, strategic form of dishonesty rather than an outright lie: the disingenuous speaker hides behind false modesty, feigned surprise, or carefully hedged statements. It appears frequently in political commentary, journalism, and everyday criticism of motives, as in "his concern for the workers seemed disingenuous." Its negative charge makes it sharper than merely calling someone evasive. The word derives from "genuine," prefixed with "dis-" to signal a departure from authenticity, and it is the direct opposite of "ingenuous," which describes innocent openness. Related forms include the adverb "disingenuously" and the noun "disingenuousness."
adjectiveNot candid or sincere, typically by pretending to know less or feel less than is actually the case; subtly dishonest in a calculated way.
- Pretending to be less knowledgeable, aware, or sincere than one actually is; lacking candor in a calculated way.
- More generally, insincere or hypocritical in manner or expression.
"Her apology struck him as disingenuous — she clearly felt no remorse at all."
"It was disingenuous of the senator to claim she had never seen the memo when her signature was on it."
"His modesty seemed a little disingenuous given how often he mentioned his awards."
Disingenuous literally contains 'genuine' — with a 'dis-' prefix that turns sincerity into its sly opposite: faking candor while concealing it.

Etymology of disingenuous
Disingenuous was formed in English in the early 17th century from the existing adjective "ingenuous," itself borrowed from Latin ingenuus, meaning "native, freeborn, hence noble, frank and honest." The prefix "dis-" reverses the sense, producing a word meaning the absence of that native frankness. It thus shares its Latin root with "genuine" (from Latin genuinus) and with "ingenious," which took a different semantic path toward clever invention. The close pairing of "ingenuous" and "disingenuous" remains one of the most commonly confused contrasts in English.
