Della's role on "Touched by an Angel” (4)
I believe the answer is:
tess
'della's role on touched by an angel' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tess that I've seen before include "- - of the d'Urbervilles" , "- of the d'Urbevilles (Hardy)" , "20 heroine" , "Lady" , "Thomas Hardy girl" .)
