Morphology
let + alone
The concessive phrase 'let alone' does not compose straightforwardly from 'let' (allow) and 'alone' (by oneself); its function is idiomatic, marking emphasis/contrast meaning 'much less' or 'not to mention'. A B1 learner who knows the individual words would be unlikely to derive this discourse-level function from the literal meanings, so it is not transparently predictable.
Etymology
Let alone gives a quick contrast: if someone cannot do an easier thing, they will almost never do a harder one. Because let can mean 'allow' and alone means 'by itself', the expression points out the second thing is 'even less likely'.
