Lingots is Duolingo's virtual currency. You mainly earn them by completing new lessons. You can spend lingots in the lingot store. There are a variety of things you can buy, including streak freeze, double or nothing, timed practice, and bonus skills.

Use them at the store. There is a store tab at the top for pc and at the bottom for mobile. You can buy extra things with them.

The Duolingo Wiki is good for this sort of question: http://duolingo.wikia.com/wiki/Lingot
