'Allis,' similar to 'allice,' is primarily found within the name 'allis shad.' On its own, it lacks common usage as a standalone word in modern English. It functions almost exclusively as a descriptor within the name of a specific fish species. 'Allis' might be considered a regional variation or archaic form. It is closely associated with its french etymological roots. Think of it as a linguistic component rather than a complete word.
