Retailer guided around Italy's capital (4)
I believe the answer is:
deli
'retailer guided around italy's capital' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'guided around italy's capital' is the wordplay.
'guided' becomes 'led' ('lead' can be a synonym of 'guide').
'around' says the letters should be written backwards.
'capital' says to take the initial letters.
The initial letter of 'italys' is 'i'.
'led' reversed gives 'del'.
'del'+'i'='DELI'
Can you help me to learn more?
(Other definitions for deli that I've seen before include "Exotic food shop" , "Shop with unusual foods" , "Special shop" , "Specialised food shop" , "Cold-meat counter" .)
