Morphology
The meaning 'physically very thick skin' is directly and compositionally derived from combining 'thick' (substantial width/density) with 'skin' (the body's external covering), so a B1 learner who knows both words can infer the meaning. This adjectival + noun pattern is cross-linguistically common and follows normal English composition, making the listed physical sense fully transparent (separate from the metaphorical 'thick-skinned' sense of emotional resilience).
Etymology
Thick skin comes from animals like elephants and rhinos whose skin is very thick and works like natural armor against thorns and insect bites. So saying an animal has 'thick skin' means its skin is physically strong and protective.
