Pronunciation

  • IPA (Ecclesiastical): [leˈɡaː.lis][1]

Forms

lēgālis (neuter lēgāle); third-declension two-termination adjective[1]

Etymology

It is from Latin lēx (“law”) + -ālis.[2][1][3]

Earliest recorded meaning

Quintilian uses it of legal questions and of the legal kind of inquiry.[4][5] Köbler dates Quintilian about 35–95/96 AD.[6]

Semantic evolution

It meant of or concerned with law, legal, a post-Augustan word that the TLL notes was rarer in prose than legitimus.[2][4][3] Quintilian renders Plato's nomothetikē as the pars legalis, legislation.[5][7] Tertullian uses it of a life lived according to the divine law, pious.[4][5]

In medieval Latin it meant legal, juridical, ruled by secular as opposed to church law, and dies legalis was a law day.[8][9] In British sources a legalis homo was a lawworthy man.[6] It lies behind French loyal and Italian leale.[1] English legal came from Old French or Latin in the mid-15th century, while loyal came from French in the 1530s and leal about 1300.[10]
