What is the difference between debt and debit?

In Personal Finance, it might help to think of it as follows:

A debit is money withdrawn from an account of money that you currently have.

But a debt is money borrowed because "i" don't have it!

In accounting, though, the term "debit" is used differently than we might think of in conversational English. In double-entry accounting a "debit" entry is used to record an increase to assets and expenses and to record a decrease in liabilities, revenues and equity.

The terms that describe "debt" in accounting are in there as well. A debt (or obligation) already paid is an "expense", while a debt (or obligation) owed is a "liability".
