Morphology
outwash = wash (semi-transparent) = out + wash
The components 'out' + 'wash' are clear, but the specialized glacial depositional meaning (sand and gravel deposited beyond a glacier) is domain-specific and not fully predictable for an average B1 learner. [Postprocessing: moved 'out' from base_words to prefix]
Etymology
Outwash comes from the simple parts out and wash, where wash means 'to move by water'. So an outwash is the sand and gravel that meltwater 'washes out' from a glacier and leaves beyond its edge.
