To owe means you need to give something to someone, usually because they gave you something first or because you promised to pay them back. When you owe money, you borrowed it and need to return it. If your friend lends you five dollars for lunch, you owe them five dollars until you pay them back.

Owing extends beyond money to include favors, gratitude, and apologies. You might owe someone a favor if they helped you with your homework, meaning you should help them when they need it. You might owe your parents gratitude for all they do for you. A student who plagiarizes owes their teacher an apology.

The feeling of owing something creates a responsibility. When you owe someone, there's an understanding that you'll follow through. That's why people say things like “I owe you one” when someone does them a kindness, acknowledging that they want to return the favor.

Sometimes people talk about what we owe to our community or country, meaning our duties as citizens. And when you accomplish something good, people might say you owe it to your hard work, meaning your effort is the reason for your success.
