Etymology
The word 'dune' entered English in the late 18th century, borrowed directly from the French word 'dune'. The French term itself originates from the Middle Dutch word 'dūne', meaning a hill or a sand hill. This Dutch root is believed to be related to the Old English 'dūn', which meant a hill or a down, a term preserved in English place names like the 'South Downs'. The ultimate origin is Proto-Germanic dūnǭ, connecting the concept of a sandy hill formed by wind to the broader, older idea of a hill or a rolling upland.
Analysis
The word 'dune' is a simplex loanword from French. It does not contain separable, meaningful morphemes within its modern English spelling.
