Supplier of good fare from India, guided westwards (4)
I believe the answer is:
deli
'supplier of good fare' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'india guided westwards' is the wordplay.
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'guided' becomes 'led' (similar in meaning).
'westwards' shows that the letters should be reversed in order (letters go right to left or from 'east' to 'west').
'i'+'led'='iled'
'iled' reversed gives 'DELI'.
'from' is the link.
Can you help me to learn more?
(Other definitions for deli that I've seen before include "place to buy food" , "small food shop" , "shop briefly" , "Shop selling processed food products" , "Specialised food shop" .)
