# Pairing vocabulary `words.txt` is EFF's Short Wordlist #2 by Joseph Bonneau / Electronic Frontier Foundation, retrieved unchanged on 2026-09-18 from https://www.eff.org/files/2016/09/08/eff_short_wordlist_2_0.txt.

The application removes the dice indices and renders `yo-yo` as `yoyo` when loading the 1,296-word list.
