Forms

immobiliser[1]

Etymology

It is formed from French immobile + -iser.[2][3] The Grand Robert calls it a learned derivative of Latin immōbilis (“immovable, of real property”),[4] and the Petit Robert derives it straight from the Latin word.[5] Littré analyses it instead as the negative prefix im- with mobiliser.[6] An earlier verb immobiliter with the same sense of “to make immobile” is recorded in 1507.[2][3]

Earliest recorded meaning

It is first recorded in 1654, in Cyrano de Bergerac's comedy Le Pédant joué, meaning “to make immobile, to stop”.[2][3]

Semantic evolution

The legal sense “to give movable property the status of real estate” appears in 1802, taken from the special sense of Latin immobilis “immovable (property)”.[2][3] In medicine the verb came to mean keeping a fractured limb still (1864).[3]

The general sense produced figurative uses: “to halt progress” (1839, George Sand) and “to make unable to act, to paralyse” (1857, Flaubert).[3] In economics immobiliser des capitaux means to tie up capital so that it is not available (before 1902, Zola).[3][7] The reflexive s'immobiliser “to come to a standstill” is not found before the end of the 19th century, in the Goncourts.[3]

English immobilize (1843) is perhaps modelled on the French verb.[8]
