Popular lecturer on French art originally in Asian country (9)
I believe the answer is:
indonesia
'country' is the definition.
(Indonesia is an example)
'popular lecturer on french art originally in asian' is the wordplay.
'popular' becomes 'in' ('in' can mean trendy).
'lecturer' becomes 'don' (don can mean an academic).
'on' is a charade indicator (letters next to each other).
'french art' becomes 'es' ('is' in French - 'art' can mean 'is' eg 'thou art').
'originally' says to take the initial letters.
The initial letters of 'in asian' is 'ia'.
'in'+'don'+'es'+'ia'='INDONESIA'
(Other definitions for indonesia that I've seen before include "Asian country, capital Jakarta" , "I said none (anag) - country" , "Muslim republic" , "somewhere in Asia" , "An ionised country of South East Asia" .)
