Fibbing, deceiving, fabricating
Fibbing, deceiving, fabricating — whichever way you slice it, you know it’s lying. However, pathological lying is different. This kind of lying goes beyond what’s considered a “fib” or a “harmless, little lie” in that the person routinely lies and does so without any logic behind it.
There are multiple names for pathological lying as well, such as mythomania, compulsive lying and pseudologia fantastica. While some of these terms may be familiar to most people, some are not, unless you’re an expert in the field.
Also, the overall consensus is that these terms all mean the same thing, but there is some debate between mental health professionals that pathological liars fall under compulsive liars. They believe it’s the compulsive liar that lies without reason, just out of habit, and that the pathological liar not only lies habitually, but also creates lies rooted in manipulation.
