👉 A backslide is a word that means to reverse or revert to something previously done, especially in a negative sense. It can refer to a backward movement on a journey or an action that leads to a reversal of direction or change from one state or situation to another. For example, if someone has been working hard for many years and finally achieves their goal, they might say "I'm backsliding" to express relief and satisfaction at having achieved what had previously seemed impossible.
