Cries uncontrollably (4)
I believe the answer is:
sobs
'cries uncontrollably' 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 noisily" , "Weeps heavily for boss" , "Given evidence of distress" , "cries uncontrollably" , "convulsions" .)
