Pronunciation

  • Classical: [fʊn.daː.mɛnˈtaː.lɪs][1]
  • Ecclesiastical: [fun.da.menˈtaː.lis][1]

Forms

fundāmentālis (neuter fundāmentāle); third-declension two-termination adjective[1]

Etymology

It is from Latin fundāmentum (“foundation”) + -ālis.[2][3][4] ⟨Fundāmentum⟩ is from fundō2 (“to lay the bottom of, found”).[4]

Earliest recorded meaning

Augustine, whom Köbler dates 354–430, speaks in a sermon of lapis ille fundāmentālis, “that foundation stone”.[5][6][4] A commentary on Job attributed to Jerome says the stone, Christ, is not only a foundation stone but also a cornerstone.[5][7]

Semantic evolution

In Late Latin it meant belonging to the foundation, chiefly in lapis fundāmentālis, a foundation stone, used figuratively of Christ;[5][2][8] Sidonius has the adverb fundāmentāliter for “utterly, from the ground up”.[5] Ecclesiastical Latin uses it for fundamental, basic.[9]

In Medieval Latin Albertus Magnus uses it in philosophy for an elementary principle, and an anatomical treatise uses it of what forms the base.[10] A British text of about 1240 speaks of stones fit to be laid in a foundation and bear the building, and compares the books of the Apostles to such stones.[11] A Hungarian source of 1425/1426 uses the neuter plural for the foundations of a tower.[12] English fundamental was modelled on it in the mid-15th century.[13]
