Sounds of grief (4)
I believe the answer is:
sobs
'sounds of grief' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sobs that I've seen before include "Weeps heavily (4)" , "Weeps audibly" , "Weeps heavily for boss" , "Cries loudly" , "cries uncontrollably" .)
