With little relief to the Italian, CIA blasted church (8)
I believe the answer is:
basilica
'church' is the definition.
(I know that basilica is a type of church)
'with little relief to the italian cia blasted' is the wordplay.
'with' says to put letters next to each other.
'little relief' becomes 'bas' (bas relief is a kind of relief. I am not sure about the 'little' bit.).
'to the italian' becomes 'il' ('the' in Italian).
'blasted' indicates an anagram.
'cia' anagrammed gives 'ica'.
'bas' next to 'il' is 'basil'.
'basil'+'ica'='BASILICA'
Can you help me to learn more?
(Other definitions for basilica that I've seen before include "Large Christian church with two rows of columns and apse at one end" , "Roman-style church" , "Form of church building" , "Palatial church" , "Magnificent church" .)
