Morphology

pityriasis + rosea

The compound is compositional: 'pityriasis' denotes a scaling skin condition and 'rosea' (Latin) means 'pink/rosy', so together they describe a pink, scaly rash. This follows regular medical naming patterns (condition + color/quality), so a learner who knows both constituents can derive the MWE meaning.

Etymology

Pityriasis rosea comes from older words: pityriasis means 'bran', small flakes, and rosea means 'pink'. So the name gives a picture of a flaky, pink rash on the body, which is why it is used for that itchy skin condition.
