Forms
residuus (feminine residua, neuter residuum); first/second-declension adjective[1]
Etymology
It is from Latin resideō (“to remain behind”) + -uus.[2][1][3] resideō is a compound of re- and sedeō (“to sit”), which de Vaan traces to Proto-Italic *sed-ē- (“to be seated”) and Proto-Indo-European *sed-eh₁- (“to be seated”), cognate with Old Irish saidid (“to sit”) and Ancient Greek ἕζομαι (hézomai, “to sit down”).[4]
Earliest recorded meaning
Its oldest attestation is a line of Accius quoted by Festus, residuos, somno deditos, where it means sitting idle, like reses.[2]
Semantic evolution
In Cicero it is what is left over from an earlier time, as a hatred he thought he had poured out but that had lingered.[2][5] In the Pro Cluentio pecūniae residuae are public funds kept back by a magistrate after his accounts.[2] It is also what remains to be done or paid, as Cicero's what was paid and what is outstanding,[2] and what is left after something is taken away, the rest; as a noun residuum is the remainder.[2][5] The jurists have an exceptiō reī residuae, against a plaintiff who had split his claims.[2] Jerome, commenting on Obadiah, uses it to render the Hebrew word sarid.[3] English residue comes from residuum through Old French, from the mid-14th century.[6]
