Formcheck is a static Website that allows to check whether the forms of a Lexeme in Wikidata conforms to the paradigm provided by a function in Wikifunctions.

It let's the user choose a language, a part of speech, the grammatical features of the output form, and a function on Wikifunctions. It then checks whether the function evaluating on the lemma indeed results in the output form.

You can select an arbitrary Z-id for the function, not just one from the given list. You can also choose arbitrary Q-ids in all the above fields, although the system tries to offer you sensible choices.
