Versioning

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:

Major

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

Minor

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

Patch

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

Implementation notes

This repository's structure is based on examples from 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 most recent update was in May 2026.)
