Forms

satisfactōrius (feminine satisfactōria, neuter satisfactōrium); first/second-declension adjective[1]

Etymology

It is formed from Latin satisfactor + -ius in Medieval Latin.[2] Köbler refers it to satisfaciō (“to make amends”).[1]

Earliest recorded meaning

Latham records it from about 1225,[1] in the sense of serving to make satisfaction or atonement for an offence or a sin.[2]

Semantic evolution

It was a word of penitential theology: Thomas of Chobham speaks of alms given by a penitent as satisfactory, and Duns Scotus and Bradwardine of a poena satisfactoria, a penalty that atones for sin.[2] It was also used of the redemptive work of Christ, as in Alexander of Hales' question whether Christ's suffering made satisfaction for every penalty.[2] Thomas Aquinas uses it as a synonym of satisfactivus, in the phrases opus satisfactorium and oratio satisfactoria.[3] English took it over in the sense “expiatory”.[4]

Timeline

  • before 1290 – An Oxford question speaks of a satisfactory reason in Christ answering to the offence.[2]
