Elevated article about, say, a European port (5)
I believe the answer is:
genoa
'a european port' is the definition.
(Italian port)
'elevated article about say' is the wordplay.
'elevated' is a reversal indicator (in a down clue, letters go up).
'article' becomes 'a' (the indefinite article in English).
'about' becomes 'on' (as in a book 'on' a certain topic).
'say' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'a'+'on'+'eg'='aoneg'
'aoneg' reversed gives 'GENOA'.
(Other definitions for genoa that I've seen before include "City of Italy" , "Seaport in northwestern Italy" , "Cake type; foresail" , "Type of rich fruit cake" , "North Italian port" .)
