A person who tells lies habitually or deliberately speaks falsely. Someone who intentionally deceives others through false statements.
From Old English 'leogere', from 'leogan' meaning 'to lie, deceive'. The word has remained remarkably stable across Germanic languages, reflecting the universal human concern with truth and deception.
Interestingly, detecting lies is much harder than people think - most individuals perform only slightly better than chance at identifying deception. This paradox exists because humans are actually quite good at lying but overconfident in their lie-detection abilities, creating a fascinating cognitive blind spot.
