Debit and Credit

Definition

The two sides of double-entry bookkeeping: debits increase assets/expenses and decrease liabilities/revenue, while credits do the opposite—intentionally confusing and the reason accounting seems designed to frustrate everyone.

Example Usage

You debit the cash account when money comes in and credit it when money goes out, unless you're thinking about it wrong, which happens to everyone.

Origin

From Italian 'debito' and 'credito,' formalized by Luca Pacioli in 1494

Fun Fact

The dual-entry system has remained virtually unchanged for 500+ years because it actually works perfectly.
