TV series to learn English by level

We count the words of every episode against the WordStudy dictionary, so you can see how much of a series you will follow at your level — and which words to learn before you press play.

Researchers who study listening say you follow a film or a show comfortably when you know about 95–98% of the words you hear. The numbers below are exactly that share: known words among all words spoken in an episode.

We start with Friends, the series learners ask about most. More series will follow.

Learn these words before you watch

WordStudy imports the words of a YouTube video, a text or a photo, keeps the ones above your level and repeats them until they stick.

Word counts come from the Friends transcripts of the Emory University character-mining corpus (Apache-2.0), cross-checked against subtitles from OpenSubtitles.org; we publish only numbers and word lists, never the dialogue. Levels (A1–C2) and translations come from the WordStudy dictionary. opensubtitles.org
