Forms
sain (feminine saine, masculine plural sains, feminine plural saines)[1] Old French sain, also written sein, and Anglo-Norman sayn and seyn.[2][3]
Etymology
It is inherited from Latin sānus (“healthy, in good condition, sensible, reasonable”).[2][4][5][6] Rey and the Petit Robert call the Latin adjective of unknown origin;[7][8] Wiktionary traces it to Proto-Indo-European *swā-n- (“healthy, whole”),[1] and Littré compared Ancient Greek σάος (sáos).[9]
Cognate with Italian sano, Spanish sano, Occitan san, Catalan sa and Portuguese são.[8][10]
Earliest recorded meaning
The TLFi's first record is in Wace's Vie de sainte Marguerite (1130–1140), of a body in good health and unharmed, where one manuscript also has sein e sauf “safe and sound”.[2] The Grand Robert and Rey date the word to about 1050,[6][7] and the GLLF, whose first record is the sense “cured” in the Roman d'Eneas (about 1130), notes that the adverb sainement shows the word to be older.[11][7]
Semantic evolution
In Old French the adjective was said of a person rid of an illness, cured (about 1145), and of one in good health (about 1155); of these uses only the opposition to malade and the phrase sain et sauf have stayed in common use.[2][7] Rey compares sain et sauf with Italian sano e salvo and Spanish sano y salvo.[7]
From about 1150 it was also applied to the mind and judgement: a person of sound mind, a sensible idea or opinion (about 1165).[2][7] The phrase sain de l'entendement (1552) gave way to sain d'esprit (1694), and Pascal's saine doctrine (1662) is a theological use, “in keeping with the teaching of the Church”.[7][2] The sense “just, loyal” of the 12th century has died out.[7]
By analogy it was said of fruit, plants and water (about 1155) and of objects and buildings in good condition, and of what is good for the health from about 1165, a use that runs parallel to santé.[7][2] It also meant “safe, free of danger” (about 1176), later said of a harbour or a coast.[2][7]

Usage notes
The Grand Robert and the Petit Robert list a separate noun sain, recorded about 1210 and kept in hunting language for the fat of the wild boar and other animals; it is first saïm (as in saindoux), from Latin sagīna (“fat”), and is a different word from the adjective.[6][8]
