A third-order class (Q24017465) is a metaclass whose instances are classes of classes of individuals. This is a bit confusing, so an example might help. We have taxonomic rank (Q427626)instance of (P31)third-order class (Q24017465), so taxonomic rank (Q427626) contains classes that are taxonomic ranks, such as family (Q35409) and species (Q7432):
- taxonomic rank (Q427626) (third-order class (Q24017465))
- subfamily (Q164280) (second-order class (Q24017414))
- Ursinae (Q7901176) (individual subfamily)
- family (Q35409) (second-order class (Q24017414))
- Ursus (Q243359) (individual genus)
- species (Q7432) (second-order class (Q24017414))
- polar bear (Q33609) (individual species)
- subfamily (Q164280) (second-order class (Q24017414))
