Pronunciation

  • Classical: [fraː.tɛrˈnaː.lɪs][1]
  • Ecclesiastical: [fra.terˈnaː.lis][1]

Forms

frāternālis (neuter frāternāle); third-declension two-termination adjective[1]

Etymology

It is formed from Latin frāternus (“brotherly”) + -ālis,[1][2] from frāter (“brother”).[1][3]

Earliest recorded meaning

It is a Medieval Latin word.[1][4] Köbler dates its first sources, Folcuin and Ratherius, to the 10th century,[4] and both use it in the sense “brotherly”: Folcuin quotes a charter speaking of brotherly consent.[3]

Semantic evolution

Besides “brotherly”, it meant belonging to a brother or to the brothers of a community, and made up of brothers;[3][5] in a monastery it described what befits a monk.[4] In Poland it was also applied to a craft guild.[6] Czech and Polish sources use it as a noun for a brother's son or daughter, a nephew or niece,[7][6] and the modius fraternalis was a measure of grain.[8]

English took it over in the early 15th century as fraternal, from Old French and directly from Medieval Latin.[2] Neo-Latin authors kept it,[9] as in the phrase fraternalis benivolentia “brotherly goodwill”.[9]
