  Hybrid definitions characteristically disjoin at least one institutional component with at least one aesthetic component, aiming thereby to accommodate both more traditional art and avant-garde art that appears to lack any significant aesthetic dimension.  (Such definitions could also be classified as institutional, on the grounds that they make provenance sufficient for being a work of art.) Hence they inherit a feature of conventionalist definitions: in appealing to art institutions, artworlds, arts, art functions, and so on, they either include substantive accounts of what it is to be an artinstitution/world/genre/-form/function, or are uninformatively circular.
