Staff leading Treasury try to pass the bar? (4,5)
I believe the answer is:
pole vault
'try to pass the bar?' is the definition.
I can't judge whether this definition defines the answer.
'staff leading treasury' is the wordplay.
'staff' becomes 'pole' (both can mean a stick).
'leading' is a charade indicator (letters next to each other) (some letters go in front of others).
'treasury' becomes 'vault' (both can mean a repository).
'pole'+'vault'='POLE-VAULT'
Can you help me to learn more?
(Other definitions for pole vault that I've seen before include "Athletic event" , "High-flying Olympic event" , "Olympic field event" , "Field event -- value plot (anag)" , "Sergey Bubka was world champion at this event" .)
