The concept of truth is central to our communication and relationships. However, sometimes it's necessary to talk about the opposite of telling the truth, which is lying. Antonyms of "tells truth" include: deceives, fibs, fabricates, falsifies, misrepresents, misleads, invents, perjures, and prevaricates. All of these words imply that someone is deliberately saying something that is not true or that they are concealing the truth. These actions can lead to misunderstandings, hurt feelings, and damage to relationships. It's important to practice honesty and integrity in all aspects of our lives to build trust with those around us.
