Morphology

undermine + credibility

Both constituents are semantically compositional: 'undermine' means to weaken or damage (often gradually) and 'credibility' means trustworthiness, so the combined meaning 'to weaken someone's trustworthiness' is directly derivable from the parts. This verb + noun composition follows common English patterns and similar logic appears cross-linguistically, making it readily understandable to a B1 learner who knows both words.

Etymology

Undermine credibility comes from the image of digging away the ground under a building: to undermine is to remove the support so the building becomes weak. Here credibility means people's 'trust', so doing things that remove that support is why the phrase means to weaken or damage someone's trust.
