Translate works on a word in its sentence or on a whole passage, and it happens entirely on your device: nothing you read is sent anywhere. Each pair of languages is a small download the first time you need it.

Translate a word

Windows

Click the word and choose Translate.

Mac

Click the word and choose Translate.

iPhone and iPad

Press and hold the word, tap More, then Translate.

The card shows the sentence with the word marked, the translation of the sentence, and the translation of the word alone beside it. A word means more in its sentence, so the sentence's translation is usually the better guide.

Translate a passage

  1. Select the passage.
  2. Choose Translate in the bar that appears.

A passage of up to about 3,000 characters is translated sentence by sentence.

Get a language the first time

The first time you translate between two languages, the card says which files are needed and how large they are, with a Download button. Each pair of languages is 14 to 26 MB. LuceVoce shows the progress, and you can Cancel. After that the pair works offline.

These languages are covered, in both directions:

  • English and Romanian
  • English and French
  • English and German
  • English and Spanish
  • English and Italian

Between two of the other languages, such as Romanian into French, LuceVoce goes through English and needs both pairs. The card says so and downloads them one after the other.

Choose the language to translate into

The book's language is translated into the language you chose last. To change it, use Into on the card, or open Settings > Study > Translation and choose Translate into.

The same place lists the languages on this device, with Download or Remove for each.

Good to know

  • Like a lookup, a translation never moves your place, pauses or starts the reading.
  • Copy on the card copies the translation.
  • The translations are made with Mozilla's Firefox translation models.
