Tips
usage
Two readings: qiánzhuàn = prequel (the modern entertainment use, 传 = biography/saga), qiánchuán = forward pass (sport, 传 = to pass). Context disambiguates — film/lit vs. ball games.
memory
前 'before' + 传 (zhuàn) 'saga, biography' — the saga that comes before the saga you already know. Same 传 as in 自传 (autobiography).
