mendacious
adjective
Did you know?
Mendacious and lying have very similar meanings, but the two are not interchangeable. Mendacious is more formal and literary, suggesting a deception harmless enough to be considered somewhat bland. Lying is more blunt, accusatory, and often confrontational. You might yell, "You lying rat!" in an argument, but you would most likely stick to the more diplomatic, "Aren't you being somewhat mendacious?" in a business meeting. Mendacious can also imply habitual untruthfulness, whereas lying is more likely to be used to identify specific instances of dishonesty.
