The term "extra space" refers to additional storage capacity or room that is available beyond what is normally required. It can be used in various contexts, such as referring to physical space, digital storage, or mental capacity. For example, if someone has an extra bedroom in their house that they don't use for sleeping, it could be referred to as "extra space." Similarly, a computer with more hard drive space than what is needed for the operating system and applications can also have "extra space" available. In other contexts, such as psychology or self-help, extra space refers to having mental capacity to think creatively, make decisions, and handle stress without feeling overwhelmed.
