Tender extract from 'Tess of the d'Urbervilles' (4)
I believe the answer is:
soft
'tender' is the definition.
('soft' can be similar in meaning to 'tender')
'extract from tess of the d'urbervilles' is the wordplay.
'extract from' indicates a hidden word (I've seen this in other clues).
'SOFT' is hidden within 'tess of the durbervilles'.
(Other definitions for soft that I've seen before include "Pliant" , "Pliable" , "Velvety" , "p. (mus.)" , "Gentle; non-alcoholic" .)
