Pronunciation

  • IPA (Classical): [ˈuː.nɪ.kʊs][1]
  • IPA (Ecclesiastical): [ˈuː.ni.kus][1]

Forms

ūnicus (feminine ūnica, neuter ūnicum, adverb ūnicē); first/second-declension adjective[1]

Etymology

It is from Latin unus (“one”) + -icus, as in bellicus and pūblicus.[2][1] ūnus continues Proto-Italic *oinos, from Proto-Indo-European *h₁óynos (“one”).[1]

Earliest recorded meaning

Plautus uses it of a person's only son, tuus unicus gnatus, and of having only one garment.[3][2] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

Its first sense is one and only, sole, as of an only son or daughter in Terence and Cicero, or the only hope in Livy.[2][5] Lucretius joins it with sōlus, “one and alone”.[5] From Afranius on it also meant having no match, singular, outstanding, as Cicero's unique example of old-time honesty.[2][6]

In medieval British Latin it was also used as a noun for an only child or son.[7] Köbler records a medieval noun for an unmarried man.[4] English unique came from French around 1600 as “single, solitary”, and as “the only one of its kind” from the 1610s.[8]
