Forms

pertināciter (comparative pertinācius, superlative pertinācissimē)[1]

Etymology

It is from Latin pertināx (“tenacious, stubborn”) + -ter.[2][1][3] pertināx is made from per- and tenāx (“tenacious”), from teneō (“to hold”),[1] which de Vaan traces to Proto-Italic *t(e)nē- and Proto-Indo-European *tn-eh₁- (“to hold”).[4]

Earliest recorded meaning

Varro uses it in his work on farming, saying that one should not keep stubbornly to the ox one has trained to the right-hand side.[2] Köbler dates it from Hirtius.[3]

Semantic evolution

It means stubbornly, with an obstinate refusal to give way: Plancus, writing to Cicero, fears seeming too stubbornly offended with Lepidus.[2] It also means persistently, through thick and thin, as in Varro.[2] Pliny the Elder uses the superlative literally, of quicksilver clinging most tenaciously to gold leaf.[2]
