There are extensive spelling dictionaries for the major languages of the world: English, Italian, French and some others; at various degrees of coverage, Mozilla has over a hundred, LibreOffice dozens. They help make Wikipedia articles in these languages more readable and professional and provide an opportunity for participation in improving spelling. Many other languages, however, don’t have spelling dictionaries. One possible way to build good spelling dictionaries would be to employ crowdsourcing, and Wikipedia editors can be a good source for this, but this approach will also require a robust system in which language experts will be able to manage the submissions: accept, reject, filter and build new versions of the spelling dictionary upon them. This can be done as a MediaWiki extension integrated with VisualEditor, and possibly use Wikidata as a backend.
