Crazed fathead ran over it and got caught (7)
I believe the answer is:
frantic
'crazed' is the definition.
(I've seen this in another clue)
'fathead ran over it and got caught' is the wordplay.
'fathead' becomes 'fra' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ran over' shows that the letters should be reversed in order (I've seen 'running over' mean this (the letters turn over to the opposite direction)).
'and' becomes 'n' (common abbreviation for 'and').
'got' means one lot of letters go next to another.
'caught' becomes 'c' (cricket abbreviation).
'it'+'n'='itn'
'itn' written backwards gives 'nti'.
'fra'+'nti'+'c'='FRANTIC'
Can you help me to learn more?
(Other definitions for frantic that I've seen before include "very worried" , "Phrenetic" , "Deranged by fear, worry etc" , "Overwrought" , "Desperate with worry" .)
