Morphology

stratum + granulosum

If a learner knows 'stratum' (layer) and understands 'granulosum' as 'granular' or 'containing granules', the compound meaning — the granular layer of the epidermis — is directly and compositionally derivable from the parts. Although the term is technical and uses a Latin form, the semantics follow a transparent 'layer + descriptive adjective' pattern common cross-linguistically, so its meaning is predictable for learners who know the constituents.

Etymology

The noun stratum granulosum comes from Latin words stratum meaning 'layer' and granulosum meaning 'full of small grains'. Picture a thin 'layer' of skin where the cells look grainy as they die and move to the surface, so the name helps you remember it is the thin granular layer just under the outer skin.
