Pronunciation

  • Classical: [ˈɡɛ.mɪ.noː][1]
  • Ecclesiastical: [ˈd͡ʒɛː.mi.no][1]

Forms

geminō (present infinitive gemināre, perfect active gemināvī, supine geminātum); first conjugation[1]

Etymology

It is from Latin geminus (“twin, double”) + -ō.[2][3][1] De Vaan traces geminus to Proto-Italic *jemno- (“paired”) and Proto-Indo-European *iemH-no- (“paired, connected”).[4]

Earliest recorded meaning

Lucilius uses it of doubling a letter, in ⟨pelliciendus⟩.[2] The TLL finds it from Terence on,[3] who has someone warn that a blow will be repeated.[2]

Semantic evolution

It means to double in number or amount:[2][5] Livy explains that six centuries are so called because they were doubled, and Quintilian uses it of doubling letters and words.[2][5] Lucretius uses it intransitively, of furniture that seems to become double.[2] It also means to repeat or do again, as Terence's repeated blow,[2] to increase by adding something like it, as Tibullus' plunder that doubles the dangers of the sea,[2] and to join two things into one: Livy has the city doubled, and Horace says that serpents are not paired with birds, nor lambs with tigers.[2] Horace also has the Corybantes clashing bronze together.[2] English geminate comes from its participle.[6]
