Forms
meritō (superlative meritissimō)[2][1] Old inscriptions have meritod, meretod and mereto.[2]
Etymology
It is an adverbial ablative of meritum (“desert, merit”), the neuter of meritus, the participle of mereō (“to earn, deserve”).[2][1] Early inscriptions spell it ⟨meritod⟩, ⟨meretod⟩ and ⟨mereto⟩, with the old ablative ending ⟨-d⟩;[2][1] Faliscan has the same form.[2][1] De Vaan traces ⟨mereō⟩ to Proto-Italic *merē- (“to earn”), perhaps from Proto-Indo-European *(s)mr-eh₁-, related to Ancient Greek μείρομαι (meíromai, “to receive one's share”) and μέρος (méros, “part, share”).[3]
Earliest recorded meaning
Plautus, Captivi: Iovī … agō grātiās meritō magnās, “I give Jupiter great thanks, as he deserves”.[2]
Semantic evolution
It means as one deserves, deservedly, and then with good reason or as a natural consequence (Lucretius: clouds rightly turn red, since they take in much of the sun's light).[2] The superlative meritissimō is “most deservedly”.[2][1] In dedications it is part of the votive formula libēns meritō, “willingly and deservedly”, abbreviated ⟨L·M⟩.[1] Church Latin glosses it “deservedly, rightly, justly”.[4]
Timeline
- c. 250–184 BC – Plautus: thanks given deservedly.[2][5]
- 96–55 BC – Lucretius in the sense “with good reason”.[2][5]

Usage notes
A rare verb meritō, meritāre, the frequentative of mereō, means to earn money regularly or to draw pay as a soldier: Cicero has a bailiff who had earned ten thousand sesterces, and Pliny says the actor Roscius earned half a million a year.[2][6]
