Forms

solide (plural solides)[1]

Etymology

It is borrowed from Latin solidus (“dense, massive, firm; whole”),[2][3][4][5] which belongs to an Indo-European root expressing the idea of “whole, entire”, like Ancient Greek ὅλος (hólos, “whole”) and Latin salvus (see sauf).[3][4] Littré noted that the inherited Old French form was “soude”, and that “solide” was remade on Latin in the 16th century.[6] The same Latin word gave sou, of which “solide” is a doublet.[1][7]

Earliest recorded meaning

Henri de Mondeville's Chirurgie (1314) has it in the sense “hard, firm”;[2][3] the word seems rare until the 16th century.[3]

Semantic evolution

In the 16th century it described what has firm consistency (viande solide, 1531), a three-dimensional body (1546) and, abstractly, what is real and lasting: Marot's solide memoire (1544), Montaigne's solide jugement and livre solide (1580).[2][3][6] In 1613 the noun solide was a geometric solid, and, from 1636 the adjective meant “able to resist, sturdy” (une couleur solide, 1842).[2][3][8] Of persons it meant “reliable, steady” (Retz, 1669), and, from the 19th century “sturdy, strong” (Balzac, 1846, avoir les reins solides).[2][3]

The noun le solide meant material advantages, money, in 1661 (Racine), and c'est du solide “it's the real thing” (1725).[2][3] Familiar phrases include solide au poste (1808) and the intensive un solide appétit (1857).[2][3] In climbing être solide is to be securely belayed (1889).[9]
