Italian maestro edges away from junction, heading for Italy (7)
I believe the answer is:
rossini
'italian maestro' is the definition.
(Italian composer Gioachino Rossini)
'edges away from junction heading for italy' is the wordplay.
'edges away from' says to take the centre.
'junction' becomes 'crossing' (crossing is a kind of junction).
'heading for' says to put letters next to each other.
'italy' becomes 'i' ().
The central letters of 'crossing' are 'rossin'.
'rossin'+'i'='ROSSINI'
(Other definitions for rossini that I've seen before include "Italian opera composer" , "Composer of 'The Barber of Seville' and 'William Tell'" , "Italian scorer" , "He composed operas" , "Barber of Seville writer" .)
