DeepL glossaries can now target language variants like pt-BR, en-US and zh-Hant (November 3, 2026)
DeepL glossary dictionaries can now target one variant, like pt-BR or de-CH. One glossary can't mix a base language and its variants.

What you get
On November 3, 2026 DeepL added glossaries for language variants. A glossary holds one dictionary per language pair. Until now a dictionary could only target a base language such as pt, and it covered every variant of that language. Now you can also make a dictionary for one variant, such as pt-BR or pt-PT. Terms that differ between Brazil and Portugal can sit side by side in one glossary.
- Supported variant targets:
de-CH,de-DE,en-GB,en-US,es-419,es-ES,fr-CA,fr-FR,pt-BR,pt-PT,zh-Hansandzh-Hant.GET /v3/languages?resource=glossaryreturns the current list. - Source languages stay base languages. Only the target can be a variant.
- How they apply: a base dictionary such as
destill applies to every variant of German. A variant dictionary such asde-CHapplies only when the request'starget_langis exactlyde-CH. - One rule per glossary: within one glossary, each language uses either the base language or its variants as targets, never both.
de-CHandde-DEcan be combined.deandde-DEcan't. Breaking this rule returns a400error.
