Poignancy seen among group at hospital (6)
I believe the answer is:
pathos
'poignancy' is the definition.
(thesaurus)
'among group at hospital' is the wordplay.
'among' indicates the answer is hidden within the clue.
'PATHOS' is hidden within 'group at hospital'.
'seen' acts as a link.
(Other definitions for pathos that I've seen before include "Hot spa (anag) - sadness" , "Quality that arouses pity or sadness" , "cause for pity" , "Quality inspiring pity" , "Something evoking pity" .)
