Forms

invalide (plural invalides)[1]

Etymology

It is borrowed from Latin invalidus (“weak, feeble, powerless”),[2][3][4] formed from the negative prefix in- and validus (“strong, robust, effective”), from valeō (“to be strong, have worth”).[5][6][7] The FEW files it under the Latin adjective.[8] It is the negative counterpart of valide.[7][4]

Earliest recorded meaning

It is first found in 1515 in a royal text collected in Isambert's Recueil général des anciennes lois françaises.[2] The TLFi and the Grand Robert read it there as “not valid” in law;[2][7] the DHLF and the GLLF date the sense “infirm, unable to work” to 1515 and the legal sense to 1542 or about 1536.[4][5]

Semantic evolution

Bloch and Wartburg note that the legal sense “null, void”, which Latin did not have, developed in French in the 16th century;[3] Martin Du Bellay asked whether a treaty was subsistant ou invalide.[6] This sense is now dated.[9][5]

The noun un invalide is first used in 1678, by Guillet, of a soldier no longer fit to serve,[2][4] and since 1718 also of anyone whom an infirmity keeps from working.[4][5] From the military sense come the name of the Hôtel des Invalides in Paris, the hospice founded by Louis XIV for disabled soldiers,[9][4] and the plural invalides “retirement after long service” (about 1800), “a disabled soldier's pension” (1821), with the slang phrase prendre ses invalides “to retire” (1867), all now out of use.[4] In computing the adjective has been taken up again for what is not valid.[4]
