Hanging loosely (6)
I believe the answer is:
floppy
'hanging loosely' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for floppy that I've seen before include "lacking tone" , "Limp - droopingLimp - drooping" , "Kind of disk" , "Tending to hang loosely" , "Hanging loosely" .)
