Noted bank trousering a million (5)
I believe the answer is:
famed
'noted' is the definition.
(synonyms)
'bank trousering a million' is the wordplay.
'bank' becomes 'Fed' (nickname for the US Federal Reserve).
'trousering' indicates putting letters inside (trouser can mean to steal).
'million' becomes 'm' (abbreviation).
'a'+'m'='am'
'fed' enclosing 'am' is 'FAMED'.
(Other definitions for famed that I've seen before include "Eminent" , "Acclaimed" , "Renowned" , "Well-known" , "Noted" .)
