Pronunciation

  • IPA (Classical): [priːˈmaː.ri.ʊs][1]
  • IPA (Ecclesiastical): [priˈmaː.ri.us][1]

Forms

prīmārius (feminine prīmāria, neuter prīmārium); first/second-declension adjective[1]

Etymology

It is from Latin primus (“first”) + -ārius.[2][1] The TLL, after Leumann, thinks it was formed from prīmus used as a noun.[3]

Earliest recorded meaning

Plautus uses it of a leading man and of a first-rate parasite.[2][4] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

It meant of the highest rank, leading, as Terence's ladies of the first rank and Cicero's leading man of the people.[2][6] It meant first-rate at something, as Pliny's first-rate warrior and Apuleius' Demosthenes, master of speaking.[2] Apuleius also uses it of things, chief, most important.[2] The Vulgate uses lapis prīmārius of the foundation stone.[6]

In medieval Latin it meant original, primordial, the first of a number and primary.[7][8] As a noun it was a chief man or governor, from Gregory the Great, and in 1323 an elementary book.[5] English primary is recorded in the early 15th century as “earliest, most basic”.[9]
