Pronunciation

  • IPA (Classical): [ˈmɛ.re.oː][1]
  • IPA (Ecclesiastical): [ˈmɛː.re.o][1]

Forms

mereō (present infinitive merēre, perfect active meruī, supine meritum); second conjugation[1] It is used both as an active mereō and as a deponent mereor; the active is usual in the senses “earn” and “serve”, the deponent with adverbs such as bene.[2]

Etymology

It is inherited from Proto-Italic *merē- (“to earn”), perhaps from Proto-Indo-European *(s)mr-eh₁- (“to earn”), from the root Proto-Indo-European *(s)mer- (“to assign, allot”).[3][1] De Vaan finds the verb hard to explain: its ⟨e⟩-grade suits neither a stative nor a causative, and Schrijver's view that it was formed from a noun does not explain its transitive use.[3] Cognate with Ancient Greek μείρομαι (meíromai, “to receive one's share”), Ancient Greek μέρος (méros, “part, share”) and Ancient Greek μόρος (móros, “fate”).[3][2][1]

Earliest recorded meaning

De Vaan's first attestation is Naevius, whom Köbler dates c. 235–200 BC.[3][4] The OLD's earliest citations are from Plautus, of earning money.[2]

Semantic evolution

It meant to receive as one's wage, to earn money, as in Plautus, and in Apuleius to earn by prostitution.[2] From Cato stīpendia merēre meant to draw a soldier's pay, to serve.[2] In Caesar it meant to win glory or reproach by one's actions, and in Plautus to deserve, merit, good or bad.[2] With adverbs, bene merērī dē meant to deserve well of someone, to do him good service, as in Plautus.[2] Döderlein notes that merēre implies an activity, whereas dignum esse “to be worthy” denotes only a quality.[5]

Its derivatives include meretrīx “courtesan”, merenda “afternoon meal” and meritum “service, reward”.[3] It survives in Spanish and Portuguese merecer and Catalan merèixer, and meritum gave English merit through Old French about 1200.[1][6]
