Italian e.g. seen wandering about holding zip (7)
I believe the answer is:
genoese
'italian' is the definition.
(I've seen this before)
'e g seen wandering about holding zip' is the wordplay.
'wandering about' indicates an anagram (I've seen this in other clues).
'holding' indicates putting letters inside.
'zip' becomes 'o' (zip can mean zero).
'e'+'g'+'seen'='egseen'
'egseen' is an anagram of 'genese'.
'genese' enclosing 'o' is 'GENOESE'.
(Other definitions for genoese that I've seen before include "Italian port's" , "from Italian city" , "From the capital of the Liguria region of Italy" , "Coming from the birthplace of Christopher Columbus" , "From an Italian port" .)
