Morphology

until + Hell + freeze + over

The phrase creates a hyperbolic image: knowing 'until', 'hell' (a very hot place) and 'freeze' lets learners infer an impossible or extremely unlikely time, so they can guess it means 'never' or 'for a very long time'. However the interpretation depends on cultural/metaphorical knowledge (that hell is hot and freezing is impossible) rather than straightforward compositional meaning, so it is not fully predictable for an average B1 learner.

Etymology

The idiom until hell freezes over imagines hell — a very hot place — freezing, which sounds impossible. That's why people use it to say something will happen 'for a very long time' or 'never'.
