Analyse nervous collapse (9)
I believe the answer is:
breakdown
I believe this clue is a double definition.
'analyse' is the first definition.
(to break something down is to analyse it)
'nervous collapse' is the second definition.
(nervous breakdown)
(Other definitions for breakdown that I've seen before include "Nervous disorder" , "Collapse - analysis" , "As result of mental stress" , "making you burst into tears?" , "Detailed analysis" .)
