River heron becomes awkward (5)
I believe the answer is:
rhone
'river' is the definition.
(I know that Rhone is a river)
'heron becomes awkward' is the wordplay.
'heron' can be anagrammed to 'RHONE'.
However, I am not clear how the anagram is indicated.
Can you help me to learn more?
(Other definitions for rhone that I've seen before include "French wine region" , "European river and glacier" , "Fr. river and wine" , "River rising in Switzerland and flowing into the Mediterranean" , "River running from the Swiss Alps to the Mediterranean" .)
