Problem: Newcomers to Wikidata don't know what an "Item" or a "Lexeme" is and don't understand the difference between both. This is not a problem with visible consequences until they want to create an entity and need to choose between "Create a new Item" (Special:NewItem) and "Create a new Lexeme" (Special:NewLexeme), when they end up creating an entity of the wrong type, sometimes they even create an Item wanting to create a Property. The introductory texts on Special:NewItem and Special:NewLexeme are proving insufficient to understand the differences and it is well known that many users do not read those texts. This can be confirmed by the fact that some users, being initially on the right special page, access the other page through the link in the introductory text and end up creating an entity of the wrong type, and also by the high percentage of newcomers who write labels and descriptions with unjustified capital letters, or write full sentences as descriptions, even though this is explained as being wrong in the corresponding introductory text.

Possible solutions: Create a special (or non-special) page that serves as an entry point ("Create an entity") to choose which entity to create based on the user's intentions and that does not use technical or Wikidata terms (no "Item", "Lexeme", etc.), improve the current special pages to highlight their differences with the interface itself (e.g. the language requested in Special:NewItem refers only to the language in which the label, description and aliases are currently written, while the language requested in Special:NewLexeme refers to the entire entity), include missing checks in the data on Special:NewItem and Special:NewLexeme to detect problems (e.g. the "lexical category" is not a lexical category, a Lexeme with the same lemma, language and lexical category already exists, etc.), include more fields on both special pages to make clear what kind of data the entity will be able to store, etc.
