The Wikipedia article on Latin declensions has this statement.
Note particularly the last sentence (underlined). The source for this section is a YouTube video, which does not support the last sentence. I have not been able to find any other reference which supports this statement. All other similar statements seem to be based on the Wikipedia article. I have spoken with my Latin teacher, who has never encountered this form.
Is this statement accurate? Where can I find an authoritative source for it?
