Definitions of deposit
a sum of money paid into a bank account
I made a deposit of $60 into my savings account.
money that you must pay when you rent something (eg a car) to cover any possible loss or damage which will be given back when you return the thing in good condition
I'll need a deposit of $100.
the first payment made towards the cost of something for which you are paying in instalments (=when you buy something by making two or more payments spread over an agreed period of time), especially when paid to make sure that no one else is able to buy it
Can I leave $50 as a deposit and pay the rest when I come to collect it?
