Forms

démolir[1]

Etymology

It is borrowed from Latin dēmōlior (“to throw down, pull down”).[2][3][1] The Latin verb is formed from dē- “down” and mōlior (“to strive to move something heavy, to build”), derived from mōlēs (“mass, structure”).[3][4][5] A present participle demoliant found in 1383 may be an earlier record;[2][3][6] Bloch and Wartburg date the verb from that year.[2][3][6]

Cognate with Walloon dimoûre, Occitan demolhir, Spanish demolir and Italian demolire.[7]

Earliest recorded meaning

In 1458 Arnoul Gréban's Mystère de la Passion uses it in the sense of taking down a building piece by piece.[2][3]

Semantic evolution

The verb had its concrete sense from the start and was used figuratively as early as the 15th century, as in Gringore, where an illness destroys the body.[2][3] In the 19th century it took the abstract sense “to ruin, overthrow” a doctrine (1826, Lamennais) and, in familiar use, “to knock out” an opponent (1801) and “to kill” (1833, Mérimée).[2][3] Littré also records it as a naval term for breaking up a ship that is out of service.[7]

Its derivative démolisseur is recorded in 1547 but was rare before Voltaire and d'Alembert used it figuratively in the 1760s;[3][6] démolissage dates from 1882.[2] The noun démolition was borrowed separately, in the 14th century, from Latin dēmōlītiō.[3][6]
