Pronunciation

  • Classical: [eːˈmɛ.re.oː][1]
  • Ecclesiastical: [eˈmɛː.re.o][1]

Forms

ēmereō (present infinitive ēmerēre, perfect active ēmeruī, supine ēmeritum); second conjugation[1] There is also a deponent ēmereor.[2][3][4]

Etymology

It is from Latin ex- + mereō (“to earn, serve”).[2][4][1] De Vaan traces mereō to Proto-Italic *mer-ē- (“to earn”) and, with a question mark, Proto-Indo-European *(s)mr-eh₁- (“to earn”), and finds its formation problematic.[5]

Earliest recorded meaning

Plautus has it first: in the Mostellaria of one term of service completed, and in the Aulularia quid ego ēmeruī malī?, “what evil have I deserved?”.[2][3]

Semantic evolution

Its chief sense is military, to serve out one's term or a number of campaigns, and absolutely to earn one's discharge, mostly in the perfect participle ēmeritus.[2] Plautus already transfers it to a courtesan whose time has been served, and Cicero to a year of duty completed.[2] It is also to earn a reward, as Propertius' honours of the robe, and to win someone's favour, as Tibullus of a sister said to have won many men's favour.[2][3] Lewis & Short note that the deponent ēmereor is perhaps not found before Augustus, and that the sense “earn” is rare and not in Cicero.[3] The Res gestae of Augustus have the participle ending ⟨-teis⟩.[4]
