Pronunciation
Forms
sānus (feminine sāna, neuter sānum, comparative sānior, adverb sānē); first/second-declension adjective[1]
Etymology
It is inherited from Proto-Italic *sāno-, mechanically Proto-Indo-European *seh₂-no-.[2][1] It might come from the root *seh₂- “to tie”, as “in place, in order”, or from *sh₂- “to satisfy” of satis “enough” and Lithuanian sotus (“sated”).[2][1] The OLD calls it doubtful.[3]
Earliest recorded meaning
De Vaan and Köbler date it from Plautus, whose lover would rather be sick than be healthier at another's cost.[2][4][3] Köbler dates Plautus c. 250–184 BC.[4]
Semantic evolution
It meant physically sound, healthy, and of things in good condition, undamaged, as Plautus' twenty minae safe and sound.[3] Most often in comedy it meant of sound mind, sane, sensible: Plautus' sānun es? “are you mad?” is frequent.[3][5] Of orators and style it meant sound and correct, as Cicero's sober, healthy speakers.[3]
Döderlein says sānus is healthy as opposed to ill, salvus safe as opposed to lost.[6] It survives in Italian sano, French sain and Spanish sano, and English sane was formed in 1721 from insane or from Latin.[1][7]
