Overtake deer to avoid liability (4,3,4)
I believe the answer is:
pass the buck
'liability' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'overtake deer to avoid' is the wordplay.
'overtake' becomes 'pass' (as in passing on a road).
'deer' becomes 'buck' (male deer).
'to' means one lot of letters go next to another (I've seen this in other clues).
'avoid' becomes 'the' (I can't explain this - if you can you should believe this answer much more).
'buck' after 'the' is 'thebuck'.
'pass'+'thebuck'='PASS THE BUCK'
Can you help me to learn more?
(Other definitions for pass the buck that I've seen before include "back out of it?" , "transfer deal, literally" , "Shirk responsibility" , "Refuse to acknowledge responsibility" , "Disclaim responsibility" .)
