Recap is a term that can have different meanings depending on the context in which it is used. Generally, however, recap refers to a summary or an abbreviated version of something that has already happened. It could be a brief restatement of events, facts, or information previously presented.
In some cases, "recap" may also refer to a re-presentation or reiteration of previous material in order to refresh one's memory or provide additional context. For example, a recap of a TV show episode might be used to remind viewers of the events that transpired during the previous week's installment before moving on to new storylines.
Overall, "recap" is often employed as a way to quickly summarize or review information for those who may have missed certain details or need a refresher on what has already been covered.
