Excitement of 60 minutes inside where money is kept (6)
I believe the answer is:
thrill
'excitement' is the definition.
(thrill is a kind of excitement)
'60 minutes inside where money is kept' is the wordplay.
'60 minutes' becomes 'hr' (synonyms).
'inside where' becomes 'til' (I can't justify this - if you can you should believe this answer much more).
'money' becomes 'l' (L can mean 'pounds').
'is kept' is an insertion indicator.
'til'+'l'='till'
'hr' put within 'till' is 'THRILL'.
'of' is the link.
Can you help me to learn more?
(Other definitions for thrill that I've seen before include "Almost pleasant sensation of fright" , "Excited sensation" , "Excited feeling" , "Tingling feeling of excitement" , "Exhilarate, excite" .)
