unimaginative (7)
I believe the answer is:
prosaic
'unimaginative' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for prosaic that I've seen before include "Hackneyed" , "Commonplace, unromantic" , "Dull - pedestrian" , "Dull -- commonplace" , "Lacking wit or imagination, dull" .)
