Forms

cōnfessus (feminine cōnfessa, neuter cōnfessum); first/second-declension adjective[1][2]

Etymology

It is from Latin cōnfiteor (“to admit, confess”), its past participle, used as an adjective.[1][3][4] That verb is a compound of com- and fateor (“to admit”).[5][2]

Italian confesso continues it.[2]

Earliest recorded meaning

Köbler's first author is Cicero.[4] The OLD's earliest example, though, is a law of the Twelve Tables: aeris cōnfessī rēbusque iūre iūdicātīs XXX diēs iūstī suntō, “for money admitted to be owed and for matters lawfully judged, let thirty days be the legal term”.[1][2]

Semantic evolution

Mostly it has the passive sense of the verb: admitted, acknowledged, as when Quintilian speaks of using Greek words that are accepted, and so generally admitted, manifest, beyond dispute.[1][2] Cicero speaks of trying to buy off a case that is plain to all, and Seneca of wasting effort on something obvious.[1] The neuter gave phrases such as ex cōnfessō, “avowedly”, in Seneca, and in cōnfessō esse, “to be undisputed”, in Pliny the Elder.[2]

In the active sense it means having confessed, and as a noun one who has admitted a debt or a crime: Sallust has dē cōnfessīs supplicium sūmere, “to punish those who have confessed”,[2] and the jurist Paulus states that cōnfessus prō iūdicātō est, “one who confesses counts as judged”.[1]

In Medieval Latin a noun cōnfessus meant a penitent who had made his confession, and later a confession.[4]
