Answer:
overdraft
Explanation:
Unlike repaying loans, which are fixed repayments over a set period, overdrafts are a form of revolving credit, much like credit cards. This means that you can add to an existing overdraft (so long as you remain within your authorised overdraft limit) – or pay it off completely one day, then dip into it the next. Overdrafts are available for as long as the bank authorises them, and for as long as you pay the fees and charges that they incur.
