A made-up or obsolete term with unclear meaning; a pseudo-scientific or archaic reference to animal-like characteristics or diminutive animal forms.
A highly obscure or invented term combining 'animal' with Italian/Spanish suffixes '-illio' suggesting diminution; likely appears only in historical medical or philosophical texts of limited circulation.
This word appears so rarely in English that it might be a ghost word—one that got into dictionaries by accident or was used by only one eccentric scholar, which is why tracking its actual history is nearly impossible.
