Wild time getting half-cut in Swiss capital (7)
I believe the answer is:
frantic
'wild' is the definition.
(similar in meaning)
'time getting half-cut in swiss capital' is the wordplay.
'getting half cut' indicates taking half.
'in' is an insertion indicator.
'swiss capital' becomes 'franc' (Swiss currency - capital can mean money).
'time' halved is 'ti'.
'ti' placed within 'franc' is 'FRANTIC'.
(Other definitions for frantic that I've seen before include "Mad" , "having kittens" , "Wildly agitated" , "Wild - frenzied" , "Overwrought" .)
