Really enjoys archaeological works (4)
I believe the answer is:
digs
I believe this is a double definition.
'really enjoys' is the first definition.
(dig can mean to appreciate something)
'archaeological works' is the second definition.
(archaeological digs)
(Other definitions for digs that I've seen before include "archaeological operations" , "Pokes sharply" , "rented accommodation" , "In brief, archaelogical excavations" , "Likes" .)
