Tabularia thesaurus data — public/vendor/thesaurus

Built by scripts/build/build-thesaurus.mjs. Versions, hashes and counts for
these files are in thesaurus.manifest.json beside this notice.

This directory is a compilation from the sources below. Everything in it that
derives from Wiktionary — register and region labels, attestation dates,
Wiktionary senses and their synonyms, idioms and proverbs and their meanings,
slang, and jargon — is licensed CC BY-SA 4.0
(https://creativecommons.org/licenses/by-sa/4.0/), and so, because they cannot
be separated, are the shard files that carry it. You may copy and adapt them
under that license. The same data, in the form the list pages use, is in the
Tabularia repository at src/tools/thesaurus/generated/.
