He provides French wine with the rent possibly (7)
I believe the answer is:
vintner
'he' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'french wine with the rent possibly' is the wordplay.
'french wine' becomes 'vin' ('wine' in French).
'with' means one lot of letters go next to another.
'possibly' indicates an anagram.
'rent' anagrammed gives 'tner'.
'vin'+'tner'='VINTNER'
'provides' acts as a link.
Can you help me to learn more?
(Other definitions for vintner that I've seen before include "A wine-merchant" , "Wine seller" , "Wine merchant" , "one in red and white?" , "Wine producer" .)
