Pieces of artwork Greek character inscribed in gents naughtily (8)
I believe the answer is:
etchings
'pieces of artwork' is the definition.
'etchings' can be an answer for 'artwork' (I've seen this before). I am not sure about the 'pieces of' bit.
'greek character inscribed in gents naughtily' is the wordplay.
'greek character' becomes 'chi' (letter from the Greek alphabet).
'inscribed in' is an insertion indicator.
'naughtily' is an anagram indicator.
'gents' with letters rearranged gives 'etngs'.
'chi' inserted within 'etngs' is 'ETCHINGS'.
Can you help me to learn more?
(Other definitions for etchings that I've seen before include "Engravings" , "Impressive marks obtained" , "Art prints" , "works of art" , "Artwork" .)
