## Fallbacks from other locales

If you have incomplete messages for a given locale and would like to use messages from another locale as a fallback, you can merge the two before passing them to `NextIntlProvider`.

```jsx
import deepmerge from 'deepmerge';

// pages/index.js
export async function getStaticProps({locale}) {
const userMessages = (await import(`../../messages/${locale}.json`)).default;
const defaultMessages = (await import(`../../messages/en.json`)).default;
const messages = deepmerge(defaultMessages, userMessages);

return {props: {messages}};
}
```
