# Languages

The Clarifai API supports many languages in addition to English. These are represented as translations of the names of concepts so that when you search by concept name or get predictions from a model's concepts you can utilize the language of your choice.

## Supported Languages

The currently supported languages are listed below.

| Language                    | Code  |

## Default Language

When you create a new Application, you must specify a default language. This will be the default language concepts are returned in when you do not explicitly set a language in an API request. You cannot change the default language. You can however change languages per request.

## List language translations by concept ID

You can see all the language translations for a given concept ID with a GET call. This call supports [pagination](/guide/api-guide/advanced-topics/pagination.md).

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://old-docs.clarifai.com/guide/api-guide/concepts/languages.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
