Morphology

weak + link

The meaning is directly compositional: 'weakest' (least strong) modifies 'link' (a connection or component), so it conveys the least strong or most vulnerable part of a system. The chain/link metaphor is common cross-linguistically and follows standard adjective + noun composition, so a B1 learner who knows both words will very likely infer the intended meaning.

Etymology

Weakest link comes from the image of a chain, where the weakest link can break first and make the whole chain fail. So calling someone the weakest link means they are the 'least effective' or most likely to cause a problem in a group.
