A break point is a term used in sports like tennis and volleyball to describe a crucial moment in the game that can change the outcome. However, there are several synonyms we can use for this expression. In tennis, we can say "game point" or "set point," which both refer to a decisive moment when a player can win a game or set. In volleyball, we can use "match point" or "set point" to describe the same situation. In business or technology, we might use "turning point," "breaking point," or "critical juncture" to indicate a crucial moment that could determine the future success or failure of a project or company.
