South American number welcomed by wine lover (8)
I believe the answer is:
casanova
'lover' is the definition.
(I've seen this before)
'south american number welcomed by wine' is the wordplay.
'south american' becomes 'sa'.
'number' becomes 'no' (abbreviation for 'number').
'welcomed by' means one lot of letters goes inside another (I've seen this in other clues).
'wine' becomes 'cava' (I have seen 'Spanish wine ' mean 'cava' so perhaps 'wine' could also mean 'cava'**).
'sa'+'no'='sano'
'sano' put into 'cava' is 'CASANOVA'.
(Other definitions for casanova that I've seen before include "Memoirist" , "Male womaniser, after 18th century Italian" , "Notorious Italian womaniser of 18th century" , "18th century Italian renowned for love affairs" , "Famous lover" .)
