Elevator direction (4)
I believe the answer is:
down
'elevator direction' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for down that I've seen before include "Where this clue is going" , "Depressed - drink" , "In a low mood; hill" , "Sad; feathers" , "Depressed; swallow" .)
