Pronunciation

  • Classical: [rɛ.ɫaːˈtiː.wʊs][1]
  • Ecclesiastical: [re.laˈtiː.vus][1]

Forms

relātīvus (feminine relātīva, neuter relātīvum, adverb relātīvē); first/second-declension adjective[1]

Etymology

It is from Latin referō (“to bring back, refer”), formed with -īvus,[1] on the participle relātus;[2] the TLL derives it from relātiō (“relation”).[3] De Vaan reconstructs the participle as Proto-Italic *tlāto-, from Proto-Indo-European *tlh₂-to- (“lifted”).[4]

Earliest recorded meaning

It is found from Arnobius (297–310 AD) on, meaning “having reference to something”.[5][3][6][7] Conte labels it Late Latin.[6]

Semantic evolution

Augustine used it in the De Trinitate for terms said in relation to something, and its adverb in vicinus et amicus relative dicuntur, “neighbour and friend are said relatively”.[5] Boethius explains that relative terms are so called because their name always refers to something.[3] The grammarians used it of pronouns that refer back: Diomedes of demonstratives, Priscian of the relative pronoun.[6][3]

In medieval Latin it also meant reciprocal, mutual or corresponding, it was used in mathematics and music, and its neuter named the relative pronoun;[8] Alcuin uses it in theology of what is said of the Father.[8] Thomas Aquinas treats it as a synonym of relatus and respectivus and the opposite of absolutus.[9] Niermeyer records relativus and relativa as nouns for a son and a daughter.[10] English borrowed it in the late 14th century, through Old French, first as a grammatical term for a relative pronoun.[2]
