Pronunciation

  • IPA (Ecclesiastical): [ˈsɛː.ku.lum][1]

Forms

saeculum n (genitive saeculī); second declension[1] Also saeclum, especially in Lucretius, and sēculum.[2][3]

Etymology

It is inherited from Proto-Italic *sai-tlo-, inherited from Proto-Indo-European *seh₂i-tlo- (“lifespan”), from the root Proto-Indo-European *seh₂i- (“to bind”).[4][5] Cognate with Welsh hoedl (“lifespan”) and Breton hoal (“age”), from Proto-Celtic *saitlo-, and with Hittite išḫai- (“to bind”) and Sanskrit स्यति (syáti, “binds”).[4][2] saeta “bristle” is from the same root.[4]

Earliest recorded meaning

Plautus uses it.[4] Köbler dates Plautus c. 250–184 BC.[6]

Semantic evolution

In Classical Latin it was a generation, people born at one time, and a breed or race, as Lucretius' races of living things.[2][7] It was the present age, as Cicero's stain of this age, a human lifetime, the span of about 33 years, and a century, as the extreme limit of life.[2][7] It was one of the ages of history, golden or silver, and in the plural future ages, as in Catullus, and per saecula “for ever”.[2]

In Christian Latin it was this world that will end, and the present life.[8][1] Through saeculāris it gave English secular, first of clergy living in the world.[5] It survives as Italian secolo and French siècle.[1]
