Although both Debit and Debt are related to finances, they have slightly different uses and pronunciation. According to the Merrian-Webster Dictionary:
Debit \ˈde-bət\: an amount of money that is taken from an account.
E.g. the bank mistakenly debited my account $200!
Debt \ˈdet\: an amount of money that you owe to a person, bank, company, etc.
E.g. He's trying to pay off gambling debts.
The company is has run up huge debts.
It's important to point out that, differently from Portuguese, the word "debt" is always used in the singular, as it follows:
- He is drowning in a sea of debt. Ele está se afogando (em um mar de) em dívidas.
- He’s been working three jobs in an attempt to get out of debt. Ele está em três empregos para tentar sair das dívidas.
- The company was in debt but is now turning a profit. A empresa estava com dívidas mas agora está começando a ter lucro.
- I am deep/heavily in debt. Eu estou atolado em dívidas.
- The family is over $50.000 in debt. A família está com mais de $50.000 em dívidas.
- More: The money a country owes another is called foreign debt.
