Beautiful old lover, who in Paris is given designated place (9)
I believe the answer is:
exquisite
'beautiful' is the definition.
(similar in meaning)
'old lover who in paris is given designated place' is the wordplay.
'old lover' becomes 'ex' (an ex-lover).
'who in paris' becomes 'qui' (French for 'who').
'is given' is a charade indicator (letters next to each other).
'designated place' becomes 'site' (eg the site of an event).
'ex'+'qui'+'site'='EXQUISITE'
(Other definitions for exquisite that I've seen before include "delightful?" , "Sharp" , "Lovely" , "Very beautiful or sensitive" , "refined" .)
