Pronunciation

  • Classical: [sɛˈkʊn.dũː][1]
  • Ecclesiastical: [seˈkun.dum][1]

Forms

secundum (+ accusative)[1]

Etymology

It is from Latin secundus (“following; second”), whose neuter is used as an adverb and a preposition.[2][3][4] De Vaan explains that adjective as a preform Proto-Italic *sekwo-ndo- (“following”), made from sequor (“to follow”), which came to be used as the ordinal “second”.[5]

Earliest recorded meaning

It is found from Plautus on,[4] both as an adverb, age i tu secundum (“go on, you follow behind”),[2][3] and as a preposition, hominum secundum litus (“people along the shore”).[2]

Semantic evolution

Plautus already uses the preposition of time, “after”, and of rank, “next to”;[2] Cato has it in an order of feeding, giving elm leaves after millet.[2] The sense “in accordance with” appears in Terence and Cicero, as in secundum tabulās testāmentī, “according to the terms of the will”, in the Verrines,[2] and in legal language it meant “in favour of” a party.[2] As an adverb it is rare: “behind”, and “in the second place”, “secondly”.[2][3]

In Medieval Latin it also meant “as regards”, “in proportion to” and “like”,[6] and scholastic Latin used secundum quid, “relatively”, “in a certain respect”.[7]
