Forms

obligātus (feminine obligāta, neuter obligātum, comparative obligātior); first/second-declension adjective[1][2]

Etymology

Used as an adjective, it is the perfect passive participle from Latin obligō (“to tie up, oblige”).[1][3] That verb is a compound of ob- and ligō1 (“to tie”), which de Vaan traces, with a question mark, to Proto-Indo-European *liǵ- (“to tie”), comparing Albanian lidh (“to tie”).[4]

Earliest recorded meaning

Köbler records it first in Cicero,[5] meaning under an obligation: ne obligati esse videantur, “so that they may not seem to be under an obligation”.[1]

Semantic evolution

It means bound by a moral or legal obligation, beholden: Cicero writes obligatus ei nihil eram, “I was not at all obliged to him”, and Pliny the Younger has the comparative obligatior.[1][2] With a genitive it means liable or responsible for something, in a law preserved in an inscription and in Ulpian.[1] Horace uses it of something owed by right, a feast due to Jupiter.[1] In medieval Latin obligatus was also a noun for a dependant of some class whose nature is unclear.[6]

Timeline

  • 81–43 BC – Cicero uses it of people under an obligation.[1][5]
  • 65–8 BC – Horace uses it of a feast owed to Jupiter.[1][5]
  • before 223 AD – Ulpian uses it of being liable in law.[1][5]
