Etymology

It is a learned word, borrowed from Latin saeculum (“generation; lifetime; age; century”).[2][3][4][1] In Christian Latin it also meant “mortal life, the world”, a calque of Ancient Greek αἰών (aiṓn, “lifetime, age”), which had itself taken this sense from a Hebrew word for “generation”; from it came saeculāris “pagan, lay”, the source of secolare.[3][5][2] The Romance words of this type, such as French siècle and Spanish siglo, are learned too, but older or dialect forms such as Piedmontese sevol show a more popular development.[3][6]

The Latin word comes from Proto-Italic *saitlom, and only Celtic has a sure cognate: Welsh hoedl and Breton hoazl “lifespan, age”.[7][3][1] De Vaan reconstructs Proto-Indo-European *seh₂i-tlo- (“lifespan”) and connects it with Hittite išhai- (“to bind”) and Sanskrit स्यति (syáti, “binds”);[7][1] Wiktionary explains the sense as the successive generations bound together in time.[7][1]

Earliest recorded meaning

DELI's first record is in Cielo d'Alcamo's contrasto (1231–1250), in the Christian sense “mortal, earthly life”.[2] The sense “a hundred years” follows in Brunetto Latini (before 1294).[2][4]

Semantic evolution

Brunetto Latini also used secolo for worldly life as opposed to religious life (before 1294), and Dante for a period of history (before 1321).[2] Boccaccio explained that “secolo, in its proper meaning, is a span of a hundred years, after the Roman usage” (‘Secolo’, secondo il suo proprio significato, è uno spazio di tempo di cento anni, secondo il romano uso).[8] Old and dialect forms include seculo, segolo and siègolo.[8][9]

The hyperbolic sense, a time that seems very long (è un secolo che…), is recorded in 1829.[2] Phrases name an age by what marks it: il secolo dei lumi for the 18th century, and il male del secolo, tuberculosis in the 19th century and later cancer and AIDS.[10][9][11] Italian also formed trasecolare (15th century), literally “to go out of the world”, hence “to be astonished”.[3] Ladin took the word as sekolo.[1]
