Forms
obaerātus (feminine obaerāta, neuter obaerātum); first/second-declension adjective[1]
Etymology
It is formed from ob (“on account of”) and aes (“bronze, money”) with the suffix -ātus,[2][1] like aerātus.[3] Varro already connects it with the word for money, speaking of a man bound to work off a debt.[3][4] aes goes back to Proto-Italic *ajos and Proto-Indo-European *h₂ei-os (“bronze”).[5]
Earliest recorded meaning
Varro uses it in the De lingua Latina to explain nexus, a free man who owed his labour as a slave until he had paid a debt;[4][3] Cicero, in the De re publica, and Caesar use the plural as a noun, “debtors”.[3][4]
Semantic evolution
As a noun it names debtors, often with clients or exiles: Caesar tells how Orgetorix gathered all his clients and obaerati,[4][3] and Livy lists exules, obaerati, capitalia ausi, exiles, debtors and men who had dared capital crimes.[3] Tacitus speaks of debtors taking refuge in a temple from their creditors.[3]
As an adjective, “in debt”, it appears in Livy, Seneca, Suetonius and Tacitus, who has the comparative obaeratior.[3][4] Seneca uses it figuratively of being indebted for kindnesses,[3] and Ambrose of the debt of sin inherited from Adam.[3]
