Morphology

let + down

The meaning 'to lower something carefully' is directly derivable from combining 'let' (allow) with 'down' (to a lower position); this is a transparent compositional particle-verb construction that follows standard English patterns. Such literal motion/position senses are cross-linguistically common and would be immediately understandable to a B1 learner who knows both constituents.

Etymology

Let down may come from the simple image of lowering something you were holding: you let it go and it falls down. So when someone 'lets you down' they lower your hopes and 'disappoint' you.
