allenate

Could you clarify what you mean by "allenate"? The term is not uniquely defined in standard references and could refer to different concepts. For example, it could be treated as a chemistry term related to allenes (such as a deprotonated allenic acid or a class of compounds/ligands derived from allene), or it could refer to a surname, a place, or a fictional concept. If you specify the intended sense, I can write a concise, neutral wiki-style article (under 300 words) appropriate to that meaning.
