Etymology

Used as an adjective, it is the perfect passive participle from Latin obstinō (“to set one's mind on”).[1][2] De Vaan explains obstinō and dēstinō as prefixed verbs built on the old nasal present of stō (“to stand”), Proto-Italic *sta-n-e/o- (“to place”), from Proto-Indo-European *st-n(e)-h₂- (“to place”).[3]

Earliest recorded meaning

Naevius has it first, addressing those who stand by obstinate.[1][4]

Semantic evolution

It means stubborn, obstinate or resolute, and in a bad sense hardened, as when Cicero writes that a man's will seems more obstinate than ever.[1] Accius apparently uses it of being held fast.[1] Church Latin glosses it obstinate, stubborn, resolute, determined.[5]

Timeline

  • c. 235–200 BC – Naevius of obstinate bystanders.[1][4]
  • 170–c. 90 BC – Accius in the sense held fast.[1][4]
  • 81–43 BC – Cicero of an obstinate will.[1][4]
