'some cheques may be' is the definition.
I can't tell whether this definition defines the answer.

'left in bank' is the wordplay.
'left' becomes 'l' (common abbreviation).
'in' indicates putting letters inside.
'l' put within 'bank' is 'BLANK'.

'as' acts as a link.

Can you help me to learn more?
