Morphology

let + up

The meaning 'to become less strong or intense' is not a straightforward compositional result of 'let' (allow) + 'up' (direction), because the particle 'up' here has an idiomatic/discourse function that signals easing or cessation rather than a literal upward motion. There is a partial relation—an easing/allowing sense—that can be guessed, but the specific phrasal-verb meaning is somewhat conventionalized and may require prior exposure, so it is not fully transparent to a B1 learner.

Etymology

The phrasal verb let up comes from the image of loosening a hold: to let something up is to relax your grip so the pressure becomes smaller. Imagine you hold a rope tight and then open your hand a little, and the pull is less, so the phrase means 'to become less strong' or 'to ease'.
