Appeal of grand Latin lover in Paris (7)
I believe the answer is:
glamour
'appeal' is the definition.
(I've seen this before)
'grand latin lover in paris' is the wordplay.
'grand' becomes 'g' (G is short for ground as in a thousand).
'latin' becomes 'l'.
'lover in paris' becomes 'amour' (French for 'lover').
'g'+'l'+'amour'='GLAMOUR'
'of' acts as a link.
(Other definitions for glamour that I've seen before include "Exciting attractiveness" , "Beauty created by clothes and make-up" , "Charm and allure" , "Voluptuous allure" , "sophisticated style" .)
