sui geniris = sui Generissui generis is an adverbial phrase from the latin meaning '' its own genus or species '' and is used in English to denote that what applies is a genus or species very singular and exceptional ( unique, unparalleled and unclassifiable ). The term was created by the scholastic philosophy to indicate an idea, an entity, or a reality that can not be included in a broader concept, i.e. that it is unique in its kind.
