# Supported languages

> Supported language codes and dialect codes

This API accepts both a base language code (`lang`) and a more specific dialect code (`dialect`).

* Use `lang` for the base language (for example `en`, `es`, `fr`, `zh`).
* Use `dialect` when you want a specific regional or stylistic variant of a language (for example US vs UK English).
