European resort — watercourse rising beneath it (8)
I believe the answer is:
spaniard
'european' is the definition.
(someone from Spain)
'resort watercourse rising beneath it' is the wordplay.
I cannot quite see how this works, but
'resort' could be 'spa' (spa is a kind of resort) and 'spa' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for spaniard that I've seen before include "Native of southern European country" , "Eg, a native of Madrid" , "Slope-measuring instrument" , "A native of Iberian country" , "European national" .)
