Why this word
A pathological liar is someone whose lying is compulsive and habitual, often without clear personal benefit or logical reason. Unlike occasional liars, a pathological liar feels a strong psychological drive to tell falsehoods constantly. This behavior is sometimes called mythomania and may be related to underlying mental health conditions. The key difference is that the lying is largely involuntary and persistent, not a conscious choice made for advantage. Understanding this helps distinguish between someone who deceives strategically and someone with a genuine compulsive lying disorder.
