Here's a breakdown:
* Recapitulation: Originally, it was a Latin word "recapitulationem" meaning "a repetition or summary."
* Recap: This shortened form emerged later, likely in the 19th century, as a more informal and convenient way to refer to the act of summarizing or repeating information.
The term "recap" has become particularly popular in the context of summarizing a story, a plot, or an event. It's now commonly used in film, television, and literature.
