Letter Path word sources (Spanish, French, German, Brazilian Portuguese)

The accepted word lists were built from Wikidata Lexemes, available under CC0:
https://www.wikidata.org/wiki/Wikidata:Lexicographical_data
https://www.wikidata.org/wiki/Wikidata:Copyright

The words selected for practice were ranked using the corresponding Unicode
Unilex frequency lists, pinned to commit

The pinned frequency files identify Unicode-DFS-2016. The Unilex repository
also carries Unicode License v3. Their complete copyright and permission
notices are available with this published word data at:

/letter-path/unilex-license.txt

The frequency data was used to rank and select a small subset of words. No
frequency values are published. Each JSON word file records its retrieval date and source SHA-256 hashes. The
source code and reproducible construction notes are in the QuickenBrain
repository at docs/letter-path-latin-provenance.md.
