What is before and after meaning?

Before and after are two words that indicate the sequences of time or events.

Before is used to describe an action, event, or occurrence that took place in the past, usually at an earlier time. For example, "I had breakfast before going to work."

After, on the other hand, indicates that an event or action occurred in the future, usually later than the present. It is often used in conjunction with before, to describe a sequence of events. For example, "After work, I went to the gym."

Before and after can also refer to changes that occur between two different states. For example, a before-and-after picture can show the visual changes that have occurred in a person's appearance over time. Similarly, in statistics, a before-and-after analysis might be performed to compare the outcomes of two different treatments or interventions.
