No badness in basset hound from Quakers' address (4)
I believe the answer is:
thou
'address' is the definition.
(I have seen 'old address' mean 'thou' so perhaps 'address' could also mean 'thou')
'no badness in basset hound from quakers'' is the wordplay.
'THOU' is hidden within the letters.
But, I am unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for thou that I've seen before include "'Holier than - - '" , "once paired with art" , "Old English pronoun" , "Archaic pronoun" , "Measure" .)
