Hello, will anyone in this corner of the internet know?

My partner and I were looking for the word that describes self-descriptive proper names, such as the type of character names that Dickens used or that we sometimes hear in our day-to-day dealings (my accountant's surname is Pennywise) - and we found the word "cratylic". What is the origin of this word? Where was it first used? And is there a less obscure word that defines the same thing?

Thank you
Ola
