Windblown ridge in Verdun excavated (4)
I believe the answer is:
dune
'windblown ridge' is the definition.
'dune' can be an answer for 'ridge' (dune is a kind of ridge). I am unsure of the 'windblown' bit.
'in verdun excavated' is the wordplay.
'in' indicates the answer is hidden within the clue.
'DUNE' is hidden within 'verdun excavated'.
Can you help me to learn more?
(Other definitions for dune that I've seen before include "Seashore sand hill" , "Ridge of wind-blown sand" , "Sandhill" , "Low hill of sand, called in a desert a barkhan" , "Sandy hill" .)
