Pronunciation

  • IPA (Classical): [pɛ.kuː.liˈaː.rɪs][1]
  • IPA (Ecclesiastical): [pe.ku.liˈaː.ris][1]

Forms

pecūliāris (neuter pecūliāre, adverb pecūliāriter); third-declension two-termination adjective[1]

Etymology

It is from pecūlium “private property” with the suffix -āris; ⟨pecūlium⟩ is from pecū “cattle”, property in cattle being the oldest kind of wealth.[2][1][3] De Vaan traces ⟨pecū⟩ to Proto-Indo-European *peḱ-u- (“cattle”).[4]

Earliest recorded meaning

The OLD's earliest citation is from Plautus, of what is one's own.[2] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

In law it meant of someone's pecūlium, the property a slave or son could hold, as in Gaius, and Ulpian's pecūliāre vīnum was wine bought from such funds; generally it meant one's own, personal, private, as in Plautus; and singular, exceptional, particular, as in Cicero.[2][6]

In Ecclesiastical Latin it meant peculiar, unique, special, and was used of the chosen people.[7][8][5] Medieval Latin used it of a monk's private things and of the worship proper to feasts.[9] English peculiar (mid-15th century, “belonging exclusively to one person”) came through Old French and directly from Latin.[3]

Timeline

  • c. 250–184 BC – Plautus uses it.[2][5]
  • 81–43 BC – Cicero uses it of the exceptional.[2][5]
  • mid-15th century – English peculiar is recorded.[3]
