With no end of hoo-ha, suspect decrease in digs, say (9)
I believe the answer is:
residence
'with no' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'end of hoo-ha suspect decrease in digs say' is the wordplay.
I cannot really see how this works, but
an anagram of 'end' is 'den' which is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for residence that I've seen before include "Dire scene (anag.)" , "bode" , "Place or house where one lives" , "The White House" , "Dwelling place" .)
