The stuff a saint is made of? (5)
I believe the answer is:
satin
'the stuff' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'a saint is made of?' is the wordplay.
'is made of?' indicates anagramming the letters.
'saint' is an anagram of 'SATIN'.
Can you help me to learn more?
(Other definitions for satin that I've seen before include "Smooth and silky" , "Smooth glossy fabric" , "Glossy textile" , "Shiny solk" , "covered with?" .)
