Out of control but, in the morning, all right (4)
I believe the answer is:
amok
'out of control' is the definition.
(I've seen this before)
'in the morning all right' is the wordplay.
'in the morning' becomes 'am' (AM on a clock).
'all right' becomes 'ok' (synonyms).
'am'+'ok'='AMOK'
'but' is the link.
(Other definitions for amok that I've seen before include "crazy" , "Run (disruptively out of control)" , "Berserk" , "Run thus to run wildly about" , "Wild and uncontrollable" .)
