His influence may make Rose change her name (4)
I believe the answer is:
eros
'his influence may' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'rose change her name' is the wordplay.
'rose' can be anagrammed to 'EROS'.
However, I'm not clear how the anagram is indicated.
'make' acts as a link.
Can you help me to learn more?
(Other definitions for eros that I've seen before include "Sore about love god" , "Winged god of love" , "Form of love" , "Rose for the love-god" , "Deity" .)
