Distinctive spirit in Somerset hospital (5)
I believe the answer is:
ethos
'distinctive spirit' is the definition.
(I've seen this before)
'in somerset hospital' is the wordplay.
'in' indicates a hidden word.
'ETHOS' can be found hidden inside 'somerset hospital'.
(Other definitions for ethos that I've seen before include "Characteristic spirit of a community - for those" , "Philosophy" , "Characteristic attitudes" , "The distinctive spirit of a culture or an era" , "Distinctive attitude (of culture, person etc)" .)
