Dropped painter outside front of gallery after lift (6)
I believe the answer is:
sagged
'dropped' is the definition.
(sagging is a kind of dropping)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for sagged that I've seen before include "Hung down loosely" , "Hung down, subsided" , "Drooped, sank" , "Hung down in the middle" , "Slumped" .)
