Not straightforward or sincere; dishonest or insincere in claiming innocence or good faith.
From dis- (opposite) + ingenuous (from Latin ingenuus, free-born, honest, sincere). The term emerged in the 17th century to describe insincere pretense of honesty.
Disingenuous people claim to be innocent while secretly knowing better—it's the difference between a lie and pretending you didn't mean to be misleading!
