Running across country makes her no different (5)
I believe the answer is:
rhone
'running across country' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'her no different' is the wordplay.
'different' is an anagram indicator (letters placed in a different order).
'her'+'no'='herno'
'herno' anagrammed gives 'RHONE'.
'makes' is the link.
Can you help me to learn more?
(Other definitions for rhone that I've seen before include "department" , "wherein runs rain in Arbroath" , "Fr. river and wine" , "French river from Alps to Mediterranean" , "European river and glacier" .)
