Non-clerical parts of Italy (5)
I believe the answer is:
laity
'non-clerical parts' is the definition.
I can't judge whether this defines the answer.
'of italy' is the wordplay.
'of' indicates an anagram (the answer comes from or 'of' the letters).
'italy' anagrammed gives 'LAITY'.
Can you help me to learn more?
(Other definitions for laity that I've seen before include "Secular persons" , "The people, not the clergy" , "They're not the clergy" , "Non-experts" , "Italy (anag)" .)
