A patient analysis? (4,5)
I believe the answer is:
case study
'a patient analysis?' is the definition.
'case study' can be an answer for 'analysis?' (I have seen 'Detailed analysis' mean 'case study' so perhaps 'analysis' could also mean 'case study'). I am not certain of the 'a patient' bit.
'patient analysis?' is the wordplay.
'patient' becomes 'case' (synonyms).
'analysis?' becomes 'study' (analysis is a kind of study).
'case'+'study'='CASE STUDY'
Can you help me to learn more?
(Other definitions for case study that I've seen before include "Detailed analysis" , "can be educational experience" , "Piece of research" , "Analysis of a particular situation" .)
