lie through one’s teeth: Idiom Meaning and Origin

The phrase "lie through one's teeth" emerged from the imagery of using teeth to speak falsehoods. Teeth, which are associated with honesty and integrity, hold symbolic significance.

Furthermore, "lie through one's teeth" conveys a sense of defiance and audacity. The image it creates of someone brazenly spreading falsehoods leaves an impression of a person who is deceitful to the core. This expression resonates due to its vivid nature and the recognition that convincing lies can be destructive.

It's important to note that "lie through one's teeth" is distinct from related idioms such as "lie like a rug" or "lie through one's nose." While all these variations convey falsehood, their nuances and origins differ. "Lie through one's teeth" specifically conveys deliberate and direct deceit.
