what does it mean to take something for granted

To "take something for granted" means to fail to appreciate or value something or someone because it is always there or assumed to always be available. It involves underestimating the importance or worth of something, often because of familiarity or assumption that it will never change or disappear. People often realize they have taken something for granted only after it is gone or lost. Another meaning is to assume something is true or will happen without questioning it. For example, someone might take their good health for granted until they fall ill, or take a person's presence or efforts for granted until they are no longer around. This phrase can apply to relationships, resources, opportunities, and everyday conveniences like the internet. In essence, taking something for granted means not fully appreciating it or assuming it is guaranteed without acknowledgment of its true value or the possibility it might be lost.
