Could this be a patient in the casualty ward? (8,4)
I believe the answer is:
dressing case
'the casualty ward?' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'could this be a patient' is the wordplay.
'could this be' becomes 'dressing' (I can't justify this - if you can you should believe this answer much more).
'a patient' becomes 'case' (synonyms).
'dressing'+'case'='DRESSING-CASE'
'in' acts as a link.
Can you help me to learn more?
(Another definition for dressing case that I've seen is " Box for toiletries".)
