Pronunciation

  • Classical: [ˈsɛu̯][1]
  • Ecclesiastical: [ˈsɛːu̯][1]

Forms

seu (conjunction)[1]

Etymology

It is the shortened form of sīve, from sī (“if”) and -ve (“or”).[2][1]

Earliest recorded meaning

Plautus has sī ego volō seu nōlō, “whether I like it or not”.[2] Köbler first records it in Terence.[3]

Semantic evolution

Seu has the meanings of sīve: “or if”, and repeated, seu … seu, “whether … or”; it introduces alternative possibilities (“either … or”), a single alternative (“or else”), and a more exact expression (“or rather”, seu potius).[2][1] The OLD notes that seu is rare in most writers of the Republic, except perhaps Caesar, and that the two forms are often combined, especially in verse (Horace: Rōmae seu fors ita iusserit exsul).[2]

Church Latin uses seu … vel for “whether … or”.[4] Medieval Latin also uses it for “and”.[5]
