It's a way of quantifying the sharpness of an image scene, the amount of detail visible at small scales, or at some rather fundamental level, how close two things can be in a scene & still be separated.

For astronomers, that's often simplified to saying "how close can two stars of equal brightness be on the sky & still separable or resolvable?"
That's not to say the stars need actually be close in space, but just how they appear on the sky.
