Saved words highlighting

PlayLingo highlights words and phrases from your vocabulary in the subtitles of every video. Here is how to turn it on or off.

FreeChecked September 15, 2026

Words you’ve saved to your vocabulary are coloured in the subtitles — in this video and in every other one. You notice them when they come back and see how they’re used in new sentences.

How it works

  1. Save a word or phrase from a video. See Saving words.
  2. Whenever it appears in subtitles, it’s shown in the highlight colour.
  3. Tap it to get an explanation in this new context.

Highlighting is on by default and is shown on all lines, not only the one playing.

Turn it on or off

  1. In the player, tap the mode button in the side controls.
  2. Tap Highlighting.
  3. Use the toggles:
    • Words from your vocabulary — highlights saved words.
    • Phrases from your vocabulary — also highlights saved phrases. This option appears only while word highlighting is on.

Changes apply right away.

Free or Pro

Saved words highlighting is free.

Common questions

A whole piece of the line is coloured — why?

It’s a phrase you saved. Phrases are highlighted as a whole. If that’s too much, switch off Phrases from your vocabulary.

I saved a word, but it isn’t highlighted

Check that Words from your vocabulary is on. If you deleted the word from your vocabulary, it’s no longer highlighted. See Editing and deleting words.

Can I highlight grammar instead?

Yes, with Part-of-speech highlighting (Pro, English).
