Work of art does yet have vitality (5,4)
I believe the answer is:
still life
'work of art' is the definition.
(I've seen this before)
'yet have vitality' is the wordplay.
'yet' becomes 'still' (synonyms).
'have' says to put letters next to each other.
'vitality' becomes 'life' (I've seen this before).
'still'+'life'='STILL-LIFE'
'does' acts as a link.
(Other definitions for still life that I've seen before include "Painting of flowers, fruit, etc" , "Painting of inanimate objects like fruit and flowers" , "Picture" , "Composition" , "Painting of a bowl of fruit, perhaps?" .)
