Lemma Handling
By default, Netflix Bilingual Subtitles does not automatically recognize different inflected forms of a word. For example, even if “play” is already in your vocabulary list, “playing” will not be highlighted.

To allow the extension to recognize all inflected forms of the same lemma, please perform tokenization by following the steps below:
Click the “w” button to tokenize the word and obtain lemma information.

After tokenization is complete, the extension will be able to recognize different forms of the same lemma.

In the pop-up window, the lemma information will also be displayed.
