Other forms: debits; debited; debiting
A debit is a payment made or charged, or the notation of the amount charged. Trying to track down the mysterious $2 debit to your bank account is almost never fruitful, but you’re bound to do it anyway.
From the Latin debere, meaning “to owe,” and just one i away from its more blunt cousin debt, a debit seems like a little word. But add an s to the end, and those charges really add up. You can use the word debit as a verb — “to debit your account,” or a noun — “the debit on your account,” but either way, a debit means you have less money than you had before!
