Frenzied in the morning all right (4)
I believe the answer is:
amok
'frenzied' is the definition.
(I've seen this before)
'morning all right' is the wordplay.
'morning' becomes 'am'.
'all right' becomes 'ok' (synonyms).
'am'+'ok'='AMOK'
'in the' is the link.
(Other definitions for amok that I've seen before include "(Run) wild, out of control" , "Frenzied, running out of control" , "Run thus to be wild and uncontrolled" , "(Run) in murderous frenzy" , "Run (disruptively out of control)" .)
