permanent
The term "permanent" refers to something that lasts indefinitely without change or interruption. It is often used to describe objects, conditions, or situations that are intended to remain in place for a long time, such as a permanent marker that leaves a lasting mark or a permanent residency status that allows individuals to live in a country indefinitely.
In various contexts, "permanent" can also relate to decisions or commitments that are not meant to be altered. For example, a permanent job typically offers long-term employment, while a permanent wave in hairstyling creates lasting curls.
