Setter contemplated resignation, discontented creative (8,6)
I believe the answer is:
portland cement
'setter' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'contemplated resignation discontented creative' is the wordplay.
'discontented' means to remove the middle letters (the word's contents are removed).
'creative' indicates an anagram.
'resignation' with its middle removed is 'rn'.
'contemplated'+'rn'='contemplatedrn'
'contemplatedrn' is an anagram of 'PORTLAND CEMENT'.
Can you help me to learn more?
(Other definitions for portland cement that I've seen before include "Bond" , "Material for building" , "hard stuff!" .)
