The most famous illustration of this theory is the legend that the City of Rome derives its name from Romulus, its supposed founder, while if Romulus ever existed at all (which most scholars doubt), then it would be far more likely that he derived his own name from an existing place name Roma, rather than vice versa.
Kõige kuulsam näide on legend, et Rooma linn sai oma nime Romuluselt, oma väidetavalt asutajalt: kui Romulus üldse olemas oli (milles enamus õpetlasi kahtleb), siis on palju tõenäolisem, et ta sai oma nime olemasolevalt kohanimelt Roma, mitte vastupidi.
