Such reactionary opinions of noted oldie: why change? (4-2-3-4)
I believe the answer is:
dyed-in-the-wool
'such reactionary opinions of noted oldie why change?' is the definition.
I can't tell whether this definition defines the answer.
'noted oldie why change?' is the wordplay.
'change?' is an anagram indicator (I've seen 'change' mean this).
'noted'+'oldie'+'why'='notedoldiewhy'
'notedoldiewhy' anagrammed gives 'DYED-IN-THE-WOOL'.
Can you help me to learn more?
(Other definitions for dyed-in-the-wool that I've seen before include "Unchanging in a particular belief" , "Retain" , "Inveterate - they do lie down (anag)" , "Invariant in beliefs" , "Of firmly fixed opinions" .)
