Pronunciation

  • /seˈɡundo/, [seˈɣ̞ũn̪.d̪o][1]

Forms

segundo (feminine segunda, masculine plural segundos, feminine plural segundas)[1] Old Spanish also wrote secundo, a more learned spelling, and segondo.[2][3][4]

Etymology

It is inherited from Latin secundus (“following; second”), by a semi-learned route: Corominas finds the treatment of the stressed vowel surprising, since popular development would have given segondo, a form Old Spanish also had.[2][5][1] The preposition según is its doublet, from secundum (“following, according to”), shortened because it was unstressed.[5][1] The verb seguir belongs to the same root.[1]

The same Latin word is Portuguese segundo, Galician segundo, Asturian segundu, Catalan segon, Occitan segon, French second, Italian secondo and Romanian secund.[3][6][1] The French word is itself a semi-learned form.[7]

The Latin word is an old participle of sequor (“to follow”) with the rare suffix -undus, so it meant “following”.[8][1] De Vaan reconstructs Proto-Italic *sekwondo- (“following”), from Proto-Indo-European *sekʷ- (“to follow”).[9] Its sense “favourable” comes from a wind or current following a boat.[1]

The noun for the unit of time comes from secundum, short for minutum secundum (“second (smaller) division”), the minute being the first sexagesimal division of the hour or degree.[10][11]

Earliest recorded meaning

Corominas dates the word to Berceo, in the first half of the 13th century.[2][5] Alfonso X's Lapidario (1250–1279) uses the ordinal in its colophon, dating the translation to el segundo anno que el noble rey don ferrando su padre gano la cibdat de seuilla “the second year after the noble king Ferdinand his father won the city of Seville”.[12]

Semantic evolution

Alfonso X's astronomical books already use segundos for the sixtieths of a minute in calculations with degrees.[12] The Diccionario de Autoridades defines the astronomical and geometrical second, and records the Latin sense “favourable” as little used.[11] The 1817 edition of the Academy's dictionary added the double turn of a lock and segunda for a hidden, usually malicious, intention.[13]

The noun for a person who follows the head of an organisation, the boxer's second and an assistant came later; the DLE now also defines the second of time by the caesium atom.[14][15] In Puerto Rico segundo has been used for a son who has the same name as his father, and in Cuba for a fish like the pompano.[16][17]
