European river where heron seen flying about (5)
I believe the answer is:
rhone
'european river' is the definition.
(river in France and Switzerland)
'heron seen flying about' is the wordplay.
'heron' can be anagrammed to 'RHONE'.
However, I'm unsure how this is indicated.
'where' is the link.
Can you help me to learn more?
(Other definitions for rhone that I've seen before include "12 wine region" , "Major French river, rising in Switzerland" , "Swiss-French river" , "River flowing from Alps to the French Med" , "River flowing through Lake Geneva" .)
