Which word signifies something that lasts over a long period?

The word "enduring" signifies something that lasts over a long period, capturing the essence of permanence or lastingness. It conveys the idea of resilience and the ability to withstand the passage of time, making it an ideal choice when describing concepts, emotions, or circumstances that are not only persistent but also meaningful over extended durations.

In contrast, the other options convey meanings opposite to endurance. "Temporary" describes something meant to last for a limited time, which directly contradicts the notion of lasting long. "Fleeting" implies a swift passage or something that is brief and quickly gone, highlighting transience rather than longevity. "Short-lived" also indicates a brief duration, emphasizing a lack of permanence. Thus, "enduring" stands out as the word that embodies the quality of lasting over an extended period.
