Which languages the site works in

“What language is the site in?” and “what language can I study in?” have different answers here, and conflating them is the mistake the language-support page exists to prevent. The interface and every written lesson are English. Study material, however, can be built from any of the Wikipedia language editions the search supports.

• Menus, help pages, lessons and assessments are English only.
• A topic opened from another Wikipedia edition is in that edition's language.
• The dictionary follows the same rule: it reads the Wiktionary edition you choose.

The wider Novus estate has a five-locale contract, and this site does not serve it: there is no localised route, and no part of the interface is translated. The page says that in plain terms instead of advertising a language switcher that would hand you an English page.
