Money deposited in bank not long ago (8)
I believe the answer is:
recently
'not long ago' is the definition.
(thesaurus)
'money deposited in bank' is the wordplay.
'money' becomes 'cent' (I've seen this before).
'deposited in' is an insertion indicator.
'bank' becomes 'rely' (I've seen this before).
'cent' inserted within 'rely' is 'RECENTLY'.
(Other definitions for recently that I've seen before include "In the near past" , "Lately" , "Of late" , "Not so long since" , "Happening not long ago" .)
