Every word here counts as known: it won't be flagged “new” in transcripts
and it lowers each clip's difficulty %. Click a word to search your videos for it or open it in
the GrammarDrills dictionary. Right-click a word in any transcript to add it here fast.
Paste a word list — one Russian word per line, or a CSV whose first column is the word
(inflected forms are fine; they resolve to the dictionary word). A header row like
word or bare is ignored.
