What does disingenuously mean?
Disingenuously is an adverb describing actions done with false sincerity — most often speech that pretends candor, innocence, or ignorance while concealing a real motive or actual knowledge. When someone asks a question they already know the answer to, or claims not to understand a situation they clearly do, they are behaving disingenuously. The word derives from 'disingenuous', which combines the negative prefix 'dis-' with 'ingenuous' (meaning open, frank, and unsophisticated), ultimately from the Latin 'ingenuus', meaning freeborn or native. Because ingenuous and ingenious look alike but mean very different things, disingenuously carries no connection to cleverness in its modern sense. The adverb appears chiefly in formal writing — political reporting, reviews, and commentary — where it signals a judgment that someone's apparent honesty is a performance. It is always critical: to act disingenuously is to deceive while wearing the mask of sincerity.
adverbIn a manner that is insincere or deceitful, especially by pretending to be candid or unaware of something one actually knows.
- In an insincere or falsely candid manner, typically by feigning innocence, ignorance, or openness to conceal a real motive or knowledge.
"She disingenuously claimed she hadn't read the memo, though it had been sitting in her inbox for a week."
"He disingenuously asked whether anyone had seen his missing keys, knowing full well they were in his pocket."
"The spokesperson disingenuously insisted that the decision had nothing to do with the scandal."
Disingenuously comes from the same Latin root as 'genius' — so calling someone's excuse disingenuous literally questions the genuineness of their inborn character.

Etymology of disingenuously
Disingenuously derives from 'disingenuous', formed in English by adding the negative prefix 'dis-' to 'ingenuous', which comes from the Latin 'ingenuus' meaning freeborn, native, or figuratively frank and honorable. 'Ingenuous' entered English in the early 17th century; 'disingenuous' followed shortly after, and the adverb developed from it. The Latin root 'gignere' (to beget) also gives us 'genuine', 'genius', and 'ingenuity', making them all distant relatives of this word about false sincerity.
