Quiet religious house reportedly in poor condition (6)
I believe the answer is:
shabby
'quiet religious house reportedly in poor condition' is the definition.
I can't judge whether this definition defines the answer.
'quiet religious house' is the wordplay.
'quiet' becomes 'sh'.
'religious house' becomes 'abby' (I am not sure about this - if you are sure you should believe this answer much more).
'sh'+'abby'='SHABBY'
Can you help me to learn more?
(Other definitions for shabby that I've seen before include "Badly clad - sort of trick?" , "Old and worn - mean" , "Of clothes, worn and threadbare (6)" , "Ill-dressed - mean" , "Worn out, dilapidated" .)
