Pronunciation
Forms
pateō (present infinitive patēre, perfect active patuī); second conjugation, no passive, no supine stem[1]
Etymology
It is inherited from Proto-Italic *patē-, a stative verb formed within Italic on a base *pat-, the same as in pandō “to spread out”, from the root Proto-Indo-European *peth₂- (“to spread”).[2][1] Cognate with Ancient Greek πετάννυμι (petánnumi, “to spread out”) and Old English fæþm (English fathom), and probably with Oscan pat- (“is open”).[3][2][4]
Earliest recorded meaning
De Vaan dates it from Plautus,[2] who wonders why a man stands outside when the doors are open to him.[3] Köbler dates Plautus c. 250–184 BC.[5]
Semantic evolution
It meant to be open, of doors, gates, buildings and roads, to be exposed to danger, and of opportunities to be open or available to someone.[3] It also meant to be visible or evident, and to extend or stretch out, as of a cave in Ennius or a country in Caesar.[3][6] Cicero says that the nostrils are always open.[6]
Its derivatives include patefaciō “to open up”, patulus “spreading” and patera “a shallow dish”.[2][1] The participle patēns gave English patent, first in letters patent, open letters granting a right.[7]
