Resounding reason principal associate is scorned by worker (8)
I believe the answer is:
resonant
'resounding' is the definition.
(I know that resounding can be written as resonant)
'reason principal associate is scorned by worker' is the wordplay.
I cannot really understand how this works, but
an anagram of 'reason' is 'resona' which is within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for resonant that I've seen before include "Tending to reinforce sounds" , "Reverberating" , "(Of sound) deep, clear and continuing to ring" , "Re-echoing" , "Ringing - earn tons (anag)" .)
