"Not for long" is a colloquial phrase used to indicate that a current situation or state of affairs will not continue or persist for an extended period of time. In essence, it suggests that whatever is happening presently is temporary, and a different outcome or change is expected or imminent.
This expression is often employed to convey a sense of reassurance or confidence that things will not remain as they are for much longer. It implies an expectation of improvement, alteration, or resolution in the near future. For example, if someone experiences a temporary setback or adversity, one might say "Don't worry, this won't last. It's not for long."
The phrase can also be used in a more literal sense, such as when referring to a short-term situation or event with a predetermined duration. In this context, "not for long" suggests that the duration is relatively brief and will eventually come to an end.
Overall, "not for long" is a concise way to express the notion that the present circumstances will soon change or cease to exist, emphasizing the temporary nature of the situation at hand. It reflects an underlying belief that whatever is happening now is not permanent and will be replaced by something different or better in the foreseeable future.
