Morphology

thick + fog

The meaning 'a dense and heavy fog' is directly and transparently derived from combining 'thick' (substantial density) with 'fog' (a low-level cloud of water droplets). This simple adjectival modification follows a standard adjective + noun composition found across languages and involves no idiomatic or metaphorical shift, so a B1 learner who knows both words will readily understand it.

Etymology

Thick fog comes from a clear picture: very heavy mist that sits close to the ground. Here, thick means packed together and fog is that low cloud, so the phrase describes a 'dense and heavy fog' that makes it hard to see.
