Account being overdrawn had to move fast (5)
I believe the answer is:
raced
'account being overdrawn' is the definition.
I can't tell whether this definition defines the answer.
'had to move fast' is the wordplay.
'had' becomes 'd' (in contractions e.g. 'I'd', 'you'd' etc).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'move fast' becomes 'race' (I've seen this before).
'd' put after 'race' is 'RACED'.
Can you help me to learn more?
(Other definitions for raced that I've seen before include "went at speed" , "Travelled at speed" , "speeded" , "Rushed" , "Cedar (anag)" .)
