Fastidious about hospital specialisation? (5)
I believe the answer is:
niche
'specialisation?' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'fastidious about hospital' is the wordplay.
'fastidious' becomes 'nice' (similar in meaning).
'about' is an insertion indicator.
'hospital' becomes 'H' (abbreviation for hospital).
'nice' placed around 'h' is 'NICHE'.
Can you help me to learn more?
(Other definitions for niche that I've seen before include "ideal position" , "hole" , "Specialised corner of the market" , "Select place in market" , "Recess in wall for statue" .)
