In a frenzy for the start of the day, all right (4)
I believe the answer is:
amok
'in a frenzy' is the definition.
(I've seen this before)
'the start of the day all right' is the wordplay.
'the start of the day' becomes 'am' (I am not sure about this - if you are sure you should believe this answer much more).
'all right' becomes 'ok' ('ok' can be a synonym of 'all right').
'am'+'ok'='AMOK'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for amok that I've seen before include "Uncontrolled or murderous way to run!" , "'Wildly, without self-control (4)'" , "Must run it" , "Run thus to run wildly about" , "(Run) wild, out of control" .)
