> The key that points to a text in an integration's `strings.json`, so the text can be translated. Integrations use keys, not English text in the code.

- In code: `translation_key`, `strings.json`
- Also: translation keys, strings.json

Entity names, states, config flow steps, errors, and exceptions all come from `strings.json`. The English text in it is uploaded to [Lokalise](https://contributors.home-assistant.io/glossary/lokalise/), where the community translates it.
