He felt rag trade improper for member of royal family (6,3,5)
I believe the answer is:
alfred the great
'member of royal family' is the definition.
The definition suggests a singular noun which matches the answer.
'he felt rag trade improper' is the wordplay.
'improper' indicates an anagram.
'he'+'felt'+'rag'+'trade'='hefeltragtrade'
'hefeltragtrade' is an anagram of 'ALFRED THE GREAT'.
'for' is the link.
Can you help me to learn more?
(Other definitions for alfred the great that I've seen before include "Resistance leader" , "One who was crowned" , "monarch - with 23a" , "King of Wessex from 871" .)
