This repo vaguely follows semver, but there is some ontological ambiguity as to whether adding and removing words from the dictionary reflects a new feature, a bug fix, or a breaking change.

I'll attempt to follow patterns observed in other CSpell dictionary repositories:

$3

- Breaking changes related to maintaining ongoing compatibility with the CSpell project.

$3

- Additions and removals of words based on recent changes to Wiktionary. This can potentially change your spell-checking results!

$3

- Dependency or other minor updates that will not affect spell-checking results.

This repository's structure is based on examples the cspell-dicts repo.

No censorship and _almost_ no curation is performed when generating the dictionary file, with some minor exceptions:

- Certain Wiktionary categories, such as "Intentional Misspellings" are excluded.
- Some parts of speech, such as "symbol", are excluded.
- Certain Wiktionary tags, such as "archaic" are excluded.

See the generate-dictionary.ts script for additional
details.

My intention is to update this dictionary with the latest words from Wiktionary at least once a year. (The mose recent update was in January 2026.)
