Jackson hit: do something better? (4,2)
I believe the answer is:
beat it
'better?' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'jackson hit do something' is the wordplay.
I cannot quite understand how this works, but
'hit' could be 'beat' (I've seen this in another clue) and 'beat' is found in the answer.
'something' could be 'it' (I've seen this in other clues) and 'it' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for beat it that I've seen before include "make off furtively" , "Scarper" , "Make off hastily" , "Sling your hook!" , "Get going" .)
