Halftime refers to a break in between two periods or halves of an event, game, performance, or activity. It is typically used when referring to sports games where there are two equal periods of play, with a short intermission or break taken at the midpoint of the game. During this time, teams can rest and regroup before continuing to play for the second half. The term "halftime" can also be used more broadly to refer to any point in time when there is an interruption or pause in a larger process or event.
