One flapping around the Rhone? (5)
I believe the answer is:
heron
'one flapping' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'around the rhone?' is the wordplay.
'around' indicates an anagram.
'rhone' anagrammed gives 'HERON'.
Can you help me to learn more?
(Other definitions for heron that I've seen before include "Wading bird with long neck and legs" , "flier" , "Long-legged long-necked wading bird" , "Large fish-eating bird" , "Grey or white long-legged wading bird" .)
