Nick's encouraging report on newly-wed's health? (9)
I believe the answer is:
bridewell
'nick's' is the definition.
(historical type of prison - 'nick' is a prison)
'encouraging report on newly-wed's health?' is the wordplay.
I cannot really see how this works, but
an anagram of 'wed' is 'dew' which is within the answer.
This may be the basis of clue (or it may be nonsense).
(Other definitions for bridewell that I've seen before include "stir once" , "jail" , "old prison" , "gaol" , "Can, perhaps" .)
