Intensive course in hospital in Notts town (8)
I believe the answer is:
workshop
'intensive course' is the definition.
(type of class or training programme)
'hospital in notts town' is the wordplay.
'hospital' becomes 'h' (abbreviation for hospital on maps).
'in' is an insertion indicator.
'notts town' becomes 'Worksop' (town in Nottinghamshire).
'h' inserted into 'worksop' is 'WORKSHOP'.
'in' is the link.
(Other definitions for workshop that I've seen before include "Seminar" , "Labour area" , "Room or building in which work or manufacture is carried on" , "Artist's studio; manufacturing room" , "Room where goods are manufactured or repaired" .)
