Points repeatedly to nurse close to collapse after advanced test (6)
I believe the answer is:
assess
'test' is the definition.
(I've seen this before)
'points repeatedly to nurse close' is the wordplay.
'points repeatedly' can mean two substitutions for 'points'.
'points' becomes 'se'.
'points' becomes 'ss'.
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'nurse close' becomes 'as' (I am not sure about this - if you are sure you should believe this answer much more).
'se'+'ss'='sess'
'sess' put after 'as' is 'ASSESS'.
'to collapse after advanced' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for assess that I've seen before include "'Evaluate, appraise (6)'" , "price" , "Make estimate or appraisal of" , "(Of a tax) determine the amount to be paid" , "'Judge, estimate (6)'" .)
