Definition: The word "apprehension" means a feeling or sense of doubt, fear, or uncertainty about something. It can also mean a state of being anxious or troubled by something. The definition of "apprehension" varies depending on context. In some religious texts, it's often used metaphorically to describe deep and lingering worry about something negative or bad happening to someone. In modern usage, though, it can be used in a more positive sense of confidence in oneself or an idea that is being considered important or significant.
