After attack, crazed nurse shoved in cupboard (8)
I believe the answer is:
credenza
'cupboard' is the definition.
(thesaurus)
'after attack crazed nurse shoved' is the wordplay.
I cannot really see how this works, but
'nurse' could be 'en' (abbreviation for enrolled nurse) and 'en' is found in the answer.
an anagram of 'crazed' is 'credza' which is within the left over letters.
This accounts for all the letters.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for credenza that I've seen before include "Italian furniture" , "A kind of sideboard or buffet" , "Might czar need this strange sideboard?" , "A kind of sideboard or cupboard" , "Zen cared about this type of sideboard" .)
