A new piece of advice in respect of hors d’oeuvre (9)
I believe the answer is:
antipasto
'hors d'oeuvre' is the definition.
(both can mean a small meal)
'a new piece of advice in respect' is the wordplay.
'new' becomes 'n' (abbreviation as in New Testament NT).
'piece of advice' becomes 'tip' (a tip is a piece of advice).
'in respect' becomes 'asto' (I can't explain this - if you can you should give a lot more credence to this answer).
'a'+'n'+'tip'+'asto'='ANTIPASTO'
'of' is the link.
Can you help me to learn more?
(Other definitions for antipasto that I've seen before include "Italian hors d'oeuvres" , "hors-d'oeuvre" , "Italian hors d'oeuvre" , "first course" , "what to eat first" .)
