As Tolkien made only few words and names in Black Speech, various fan attempts to invent new words and translate text were made in self-published journals (like “Vinyar Tengwar” and “Quettar”) and (e)mailing lists (Tolklang). These additions to Black Speech were amateurish but became a basis of modern dialects and almost a canon despite their flaws. I do not cover later inventions because they haven't got such impact on Neo Black Speech. So, notorious works were:

• Full Ring Verse translation by Elerrina
• Olympic Verse by Lalaith
• Orc greeting by Andrew
