Evidently he made capital love (5)
I believe the answer is:
romeo
'evidently he' is the definition.
The definition suggests a singular noun which matches the answer.
'capital love' is the wordplay.
'capital' becomes 'rome' (capital of Italy).
'love' becomes 'o' (love means zero in tennis).
'rome'+'o'='ROMEO'
'made' acts as a link.
Can you help me to learn more?
(Other definitions for romeo that I've seen before include "Juliet's immortal lover" , "He loved" , "He was known for loving" , "Amorous male" , "Ladies' man" .)
