Spelling validation during preparation only: LibreOffice English Hunspell dictionaries, https://github.com/LibreOffice/dictionaries/tree/master/en (en_GB and en_US). These validation dictionaries are not redistributed in the game. The two frequency corpora are different in age and genre; these lists are corpus-based rankings of eligible playable words, not an exhaustive dictionary or universal ranking of English. Game additions maintained separately: MU, MUTE, MUTED, MUTES, MUTING, FIDGET, BASES, ONES. These do not replace frequency-ranked entries. Expanded dictionaries (15 October 2026) The original 10,000-word lists above are retained in full. Added words are the A-Z entries of 2-15 letters in ENABLE1 accepted by the corresponding LibreOffice en_GB or en_US Hunspell spelling dictionary. No frequency cutoff is applied to additions. This is a broader playable word list, not an exhaustive dictionary. ENABLE: Enhanced North American Benchmark LExicon, Alan Beale and M. Cooper; public domain. Word-list mirror: https://github.com/dolph/dictionary/blob/master/enable1.txt Public-domain declaration and source credits: https://github.com/BartMassey/wordlists/blob/main/README-enable2k.txt The ENABLE portion remains freely redistributable.
