Forms
infirme (plural infirmes)[1] Old French enferm, enferme and enfer “weak, sick”, in use until the 16th century.[2][3][4]
Etymology
It is inherited from Old French enferm remade after borrowed from Latin īnfirmus (“weak in body or mind”).[2][4][5] The Old French adjective, recorded from about 1050, was the inherited outcome of the same Latin word.[4][2] The learned refashioning was needed because the old form had become identical with some forms of the verb enfermer, according to Gilliéron.[2] In the 16th century Pasquier noted that the French had taken back the Latin ⟨i⟩ in this word and in infirmité.[3][6]
The Latin word is formed from in- (“not”) and firmus (“firm, strong”), the source of ferme1; in modern French the two adjectives are no longer felt to be related.[4][7]
Cognate with Old Occitan enferm, Spanish enfermo and Italian infermo.[6]
Earliest recorded meaning
The old form is found about 1050 in the Vie de saint Alexis: Tut soie anferm, si m' pais pur sue amor (“though I am sick, feed me for the love of God”).[6][7] The form infirme is recorded from 1247 but is rare before the 16th century;[3][8] about 1265 the statutes of the Hôtels-Dieu use it for “sick”.[7][4]
Semantic evolution
In the 16th and 17th centuries the word kept the Latin sense “lacking strength, physical or moral”: Marot speaks of mon cuer jadis infirme (1539).[2][4] It was also said of a weak plant (1690).[4] With Molière (1673) it came to mean subject to infirmities, and it now applies to a person who has lost the use of a limb or organ; it is used as a noun from 1690.[2][7] In this medical sense it differs from both the Old French word and Latin.[3] The weak sense survives only as a literary archaism, as in Pascal's l’esprit est prompt et la chair infirme.[7][8]
