...out daunts drunk carrying nothing over (7)
I believe the answer is:
astound
'out daunts drunk carrying nothing over' is the definition.
I can't tell whether this definition defines the answer.
'out daunts drunk carrying nothing over' is the wordplay.
'out' indicates putting letters inside.
'drunk' indicates anagramming the letters.
'carrying nothing over' becomes 'o' (I can't explain this - if you can you should give a lot more credence to this answer).
'daunts' anagrammed gives 'astund'.
'astund' placed around 'o' is 'ASTOUND'.
Can you help me to learn more?
(Other definitions for astound that I've seen before include "Stupefy" , "Flabbergast" , "Shock, surprise greatly" , "Bewilder" , "Stagger" .)
