Morphology

lichen + ruber + planus

This is a Latin medical name rather than a regular English phrase; its constituents ('ruber', 'planus') are obscure/non‑English and would not be known by a B1 learner, and even knowing 'lichen' does not yield the specific diagnosis. The term is specialized and non-compositional for typical learners, so its meaning cannot be derived from its parts without medical/Latin knowledge.

Etymology

Lichen ruber planus comes from Latin words: lichen meaning a plant-like or scaly growth, ruber meaning 'red' and planus meaning 'flat'. So the name describes the disease's 'red', 'flat' bumps that often itch.
