Forms

ēmeritus (feminine ēmerita, neuter ēmeritum); first/second-declension adjective; as a noun, ēmeritus m (genitive ēmeritī); second declension[1][2]

Etymology

Used as an adjective, it is the perfect participle from Latin ēmereō (“to serve out, earn”), also of the deponent ēmereor.[1][2][3] The verb is from Latin ex- + mereō (“to earn”),[1] and de Vaan records it from Plautus on.[4]

Earliest recorded meaning

It first appears in Plautus, where a single campaign has been served out (ēmeritum est stīpendium).[1][5]

Semantic evolution

With stīpendia or annī it describes military service completed, as in Sallust, Cicero, Livy and Ovid.[6][1] Valerius Maximus uses the deponent participle of a soldier who had served out his campaigns.[1][2] As a noun, ēmeritus is a soldier who has finished his time, a veteran, in Lucan, Tacitus, Suetonius and inscriptions.[1][6]

In poetry it is transferred to whatever has finished its work: Ovid has the countryman hang up his ēmeritum arātrum, the plough that has done its service, Lucan ships drawn back from the docks, Pliny the Elder a spent vine shoot and Statius old hounds.[1][2] Of time it means completed, as Ovid's year that has run its courses.[1][2]

In Ecclesiastical Latin it describes a retired person, and the neuter ēmeritum is a pension.[7] The medieval noun still meant a veteran soldier.[5] Italian emerito continues it.[3]
