At bay

In the context of a difficult or threatening situation, "at bay" describes a state where something is held off or prevented from closing in or overcoming. It signifies a temporary containment or check, often achieved through resistance or defensive measures. The threat remains present and potentially powerful, but its immediate impact is neutralized or postponed.

The phrase often implies a precarious situation where continued effort is required to maintain the defensive position. It suggests that the threat, problem, or pursuer could overcome the defense if vigilance or resistance flags. It does not mean the threat is gone, but rather that it is being actively managed or held back.
