Morphology

pea + soup

The sense 'a thick, yellowish fog' is a figurative comparison to the consistency and color of pea soup, not a literal combination of the nouns 'pea' and 'soup'. A B1 learner who knows the words would most likely interpret it as a food item and would not reliably infer the meteorological meaning without prior exposure, so the expression is idiomatic rather than transparently compositional.

Etymology

The informal meaning of pea soup comes from the look of old city fog. People said the fog was so thick and yellow-green that it looked like a bowl of pea soup, so the phrase came to mean 'heavy fog'.
