Intimate female friend in Paris, duplicitous one (8)
I believe the answer is:
familiar
'intimate' is the definition.
(I've seen this before)
'female friend in paris duplicitous one' is the wordplay.
'female' becomes 'f' (common abbreviation).
'friend in paris' becomes 'ami' (I've seen this in another clue).
'duplicitous one' becomes 'liar' (I can't justify this - if you can you should believe this answer much more).
'f'+'ami'+'liar'='FAMILIAR'
Can you help me to learn more?
(Other definitions for familiar that I've seen before include "Well known like witch's servant" , "Intimate" , "Au fait" , "Usual; well known" , "Well-known, easily recognisable" .)
