He'll give you a hug, love (4)
I believe the answer is:
hugo
'he'll give you a' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'hug love' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'hug'+'o'='HUGO'
Can you help me to learn more?
(Other definitions for hugo that I've seen before include "Fr. Author; Sci-fi award" , "Victor ---; --- Wolf" , "French romantic writer, Victor, d. 1885" , "Boy" , "Victor maybe" .)
