Language tools

You can use Capti to look up translations (100+ languages) and definitions of words and phrases and build custom, context-specific word lists.

To look up a word or a phrase a you can select it in text and click either Translate or Define in the contextual menu that will automatically appear.

To provide the most appropriate translation or definition, Capti is taking into consideration the context in which the word or a phrase are found:

  • Phraseology - If you look up a single word from a sentence, Capti will check if the word is used as a part of a phrase. If it is, the translation or definition for that phrase will be displayed. For example, if you have a sentence "I made a point." and you look up the word "point" Capti will show results for "made a point".
  • Morphology - Each instance of a word or a phrase in the text has a separate, context specific translation and definition. Capti takes into account the word's part of speech, tense, and other factors.
  • Lemmatization - If you look up a word that is not in its base form, two results will be displayed: one for the word you looked up and one for its base (lemmatized) form. For example, if the word you looked up was "building" and it was used as a verb, then you will see results for "building" (present participle) and "build" (verb).

You can also:

  • View word's phonetic transcription and listen to the word pronunciation.
  • Open a separate browser tab with expanded review of word's parts of speech, etymology, examples, etc.
  • Click the Add button to save dictionary translation or definition of words and phrases into track's word list. If translation or definition is not provided, you can click on the word or phrase in the bottom of the dialog.
