The term "predefined" refers to something that is already established, predetermined or fixed beforehand. It means that certain criteria, rules, standards or expectations have been set in advance and are not subject to change unless there is a valid reason for doing so.
In other words, predefined implies that the outcome or result of an action has already been determined based on previously established guidelines, parameters or limitations. This term can be used in various contexts such as programming languages where certain functions and operations are "predefined" to make it easier for developers to write code efficiently. Similarly, in everyday life situations, predefined could refer to societal norms, cultural expectations, or traditional roles that dictate how people should behave or what they should do in a given situation.
