Sanctimonious German writer's filthy accommodation (6)
I believe the answer is:
pigpen
'filthy accommodation' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'sanctimonious german writer's' is the wordplay.
'sanctimonious' becomes 'pi' (old-fashioned term for pious).
'german' becomes 'g' (abbreviation).
'writer' becomes 'pen' (something which writes).
'pi'+'g'+'pen'='PIGPEN'
Can you help me to learn more?
(Other definitions for pigpen that I've seen before include "tip" , "that accommodates swine" , "Sty for swine" , "Sty (American)" .)
