"All at once" is an idiomatic phrase that describes a situation or action happening simultaneously or in a single instance, without warning or preparation. It refers to the occurrence or realization of multiple things, events, or aspects simultaneously, rather than sequentially or incrementally. This phrase implies an abrupt, sudden, or unexpected occurrence of multiple factors at the same time.
The term can be used in various contexts to depict circumstances where numerous events, actions, or emotions converge simultaneously, creating an intense or overwhelming situation. For instance, if an individual receives multiple pieces of important news simultaneously, they can be said to have received them "all at once." Similarly, if a person experiences multiple strong emotions simultaneously, it can be described as feeling "all at once".
The phrase helps communicate the suddenness and intensity of a situation where various elements come together simultaneously, often leaving an individual feeling surprised, caught off guard, or overwhelmed. It emphasizes the notion that several events or factors, instead of occurring gradually or sequentially, suddenly manifest themselves at the same time.
Overall, "all at once" signifies the simultaneous occurrence or realization of multiple elements, actions, or events in an unexpected or sudden manner, often leading to a heightened experience or situation.
