Article with suggestion concerning appetiser (9)
I believe the answer is:
antipasto
'appetiser' is the definition.
(I've seen this before)
'article with suggestion concerning' is the wordplay.
'article' becomes 'an' (indefinite article).
'with' means one lot of letters go next to another.
'suggestion' becomes 'tip' (tip is a kind of suggestion).
'concerning' becomes 'asto' (I've seen this before).
'an'+'tip'+'asto'='ANTIPASTO'
(Other definitions for antipasto that I've seen before include "hors-d'oeuvre" , "first course" , "what to eat first" , "course of hors d'oeuvres" , "Italian food" .)
