rigeō (present infinitive rigēre); second conjugation, no perfect or supine stems[1]
Etymology
It is inherited from Proto-Italic *rig-ē-, inherited from Proto-Indo-European *Hriǵ-eh₁- (“to be stretched, be stiff”), a stative verb.[2][1] Cognate with Old Irish rigid (“stretches”) and Middle Irish ring (“torture”).[2][1] Pokorny derived it from regō “to stretch, rule”, which de Vaan finds unlikely, and Walde and Hofmann from the root of frīgus “cold”, which would not explain the short vowel.[2] De Vaan follows Schumacher in positing one verb *reiǵ- “to stretch, bind”.[2] Lewis and Short compared Ancient Greek ῥιγέω (rhigéō, “to shiver”).[3]
Earliest recorded meaning
De Vaan dates it from Cicero, though rigidus is older.[2] Köbler dates Cicero 81–43 BC.[4]
Semantic evolution
It meant to be stiff, rigid or unbending, as Virgil's cloak stiff with gold embroidery and the boxing gloves stiff with lead and iron, and of eyes to be fixed in a stare.[5] Cicero uses it of the parts of the earth stiff with cold, and it was used of limbs numb with cold and of freezing water.[5][3] It also meant to stand stiffly erect, and of hair to stand on end, as Ovid's comae terrōre rigēbant.[5][6]
