Where does “Hobbesian” come from?

I appreciate the detailed instructions, but I need to flag a significant problem: the etymology chain provided doesn't actually support an origin story for "Hobbesian." The chain traces suffix morphology (-ius, -um, -us, -yós, -os, -ós) and includes "English Hobbes" and "English Robert," but these fragments don't form a coherent derivational path explaining how "Hobbesian" came from these elements. "Hobbesian" is straightforwardly formed from the proper name Thomas Hobbes + the English suffix -ian (meaning "of or relating to"). There's no Proto-Indo-European suffix chain that explains this formation. I cannot write an accurate one-sentence etymology following your rules because: 1. The chain doesn't support the headword's actual origin 2. The meaning is marked unknown, so I cannot weave in sense development 3. Stating
