MT glossaries are a feature available in the Phrase Language AI add-on.

Up to 10 glossaries can be attached to a Phrase Language AI profile (or activated in Phrase Language AI if profiles are not used) with a maximum of 50,000 entries in total. Total number of glossaries is limited by purchased plan.

Once a glossary is attached to a profile, edits made to that glossary are not detected by the profile. To propagate glossary edits to a profile, the glossary must be removed from the profile and reattached.

Available MT glossaries are accessible by clicking on the MT glossaries tab in the Phrase Language AI page. The MT glossaries tab presents a searchable list of glossaries, with different columns providing specific information about each glossary.

MT glossaries ensure terminology is handled correctly by MT engines. They function in a similar manner to term bases but are used by machine translation engines instead of linguists. Terms added to a glossary are applied by the machine translation engine before being seen by the linguist ensuring provided terms are consistently substituted.

Use cases

  • Product names

    Phrase Language AI must translate to Phrase Language AI.

  • Ambiguous words

    The word bat can mean a piece of sports equipment or an animal. If translating words about sports, use a glossary to feed the Cloud Translation API the sports translation of bat and not the translation for the animal.

  • Borrowed words

    Bouillabaisse in French translates to bouillabaisse in English. The English language borrowed the word from the French in the 19th century. An English speaker lacking French cultural context may not know that bouillabaisse is a fish stew dish. A glossary can override a translation so that bouillabaisse from French translates to fish stew in English.

Glossaries are not supported by all machine translation engines and are only available through Phrase Language AI. If supported, this will be indicated in the machine translation profile along with supported glossary languages.

If glossaries contain duplicates, they might be rejected by some MT engines.

The glossary and job languages (and their codes) should correlate in order for the glossary to be applied.


Depending on file size, it can take up to 15 minutes until a glossary is attached.
