Pronunciation

Forms

fondamental (feminine fondamentale, masculine plural fondamentaux, feminine plural fondamentales)[1]

Etymology

It is borrowed from Late Latin fundāmentālis (“forming the foundation of something”),[2][3][4][5] a word of Christian Latin,[2] from fundāmentum (“foundation”).[5][4][1] The word is thus related to fondement.[3][4]

Earliest recorded meaning

It is first found before 1475 in the Chronique of Chastellain, in fondamental orgueil, meaning “forming the essential part of something”.[2][3]

Semantic evolution

The sense “basic, essential” has lasted into modern French.[3] Montaigne used the word in 1580 in senses close to the modern ones,[6] while the concrete sense “serving as the foundation of a building”, as in pierre fondamentale, is recorded by Furetière in 1690 and is now dated.[6][2]

In music son fondamental (1701) and note fondamentale (1721) name the note on which a chord is built.[3][2] In science recherche fondamentale (1960), research directed at the theory of a field, stands in contrast to applied research.[3][2] The adjective gave fondamentalement, which first meant “down to the foundations” in architecture, and in the 20th century fondamentalisme and fondamentaliste.[3]
