Specialized hospital in pleasant surroundings? (5)
I believe the answer is:
niche
'specialized' is the definition.
(I've seen this in another clue)
'hospital in pleasant surroundings?' is the wordplay.
'hospital' becomes 'h' (abbreviation for hospital on maps).
'in pleasant' becomes 'nice' (associated in meaning. I am not sure about the 'in' bit.).
'surroundings?' means one lot of letters goes inside another.
'h' placed within 'nice' is 'NICHE'.
(Other definitions for niche that I've seen before include "Cosy spot" , "Recess - suitable position" , "Select place in market" , "Comfortable position" , "somewhere comfortable" .)
