Synonym Usage
Falsehood, fib, lie, untruth refer to something untrue or incorrect. A falsehood is a statement that distorts or suppresses the truth, in order to deceive: to tell a falsehood about one's ancestry in order to gain acceptance. A fib denotes a trivial falsehood, and is often used to characterize that which is not strictly true: a polite fib. A lie is a vicious falsehood: to tell a lie about one's neighbor. An untruth is an incorrect statement, either intentionally misleading (less harsh, however, than falsehood or lie) or arising from misunderstanding or ignorance: I'm afraid you are telling an untruth.

Explanation
A falsehood is a lie. If your mom has an uncanny knack for knowing when you're telling a falsehood, it means she always knows when you're stretching the truth. The noun falsehood is a slightly fancy or old-fashioned way of saying "lie." It's hard to ever completely trust a friend again once he's told you a falsehood, although sometimes people tell small falsehoods simply to make others feel better. Telling your aunt her pink hair looks fine is a small falsehood, while lying about your grades on a college application is a pretty big falsehood. The Latin root is falsus, "deceived or erroneous."
