How it's used

This idiom describes someone whose words do not match their inner thoughts, often implying a lack of sincerity or honesty. It is frequently used to warn others about someone's unreliable character rather than just describing a single instance of lying. Unlike simple lying, it specifically highlights the disconnect between the outward expression and the genuine intent.

Common mistake

Learners sometimes mistake this for simply lying or cheating, but it specifically refers to the mismatch between what is said and what is felt. It is not used for factual errors or objective falsehoods, but rather for emotional or intentional insincerity.
