Pronunciation

  • Classical: [ɪmˈmeː.rẽːs][1]
  • Ecclesiastical: [imˈmɛː.rens][1]

Forms

immerēns (genitive immerentis); third-declension one-termination adjective[1]

Etymology

It is from Latin in- (“not”) + merēns (“deserving”), the negative prefix with the present participle of mereō (“to earn, deserve”).[2][1][3] De Vaan lists it among the derivatives of that verb, which he traces to Proto-Italic *mer-ē- (“to earn”) and, with a query, to Proto-Indo-European *(s)mr-eh₁- (“to earn”), comparing Ancient Greek μείρομαι (meíromai, “to receive one's share”).[4]

Earliest recorded meaning

De Vaan and Köbler date it from Plautus,[4][5] whose Curculio has male mereri de immerente inscitia est, “to treat badly someone who does not deserve it is folly”.[3][6]

Semantic evolution

It means not deserving punishment or harm, blameless, innocent: Terence has a wrong done to someone immerenti, and Catullus speaks of a cough that his belly gave him, non immerenti, one who had deserved it.[3][6] Lucretius splits it as inque merentes, of the innocent struck by lightning, and Horace has a tree fall on the head of its blameless master.[6][3][7] Lewis and Short call it poetic and post-Augustan in prose.[6] Valerius Maximus applies it to things, quaedam immerentia, and also has the adverb immerenter, undeservedly.[6][8] In Fronto and Cyprian it means undeserving of a benefit, unworthy.[2][7] In a 1555 statute of St John's College, Oxford, the writer calls himself immerentem et indignum, undeserving and unworthy.[9]
