MediaWiki:Wikibase-newlexeme-summary/en

You are about to create a Lexeme to store lexicographical data (e.g. language, etymology, inflections, etc.) about a word or phrase, not general data about the entity or concept to which it refers. If you want to store general data (e.g. date of birth, opening date, author, image, country, coordinates, website, etc.), you need to create an Item instead.
