Ultimate origin

Pronunciation

  • Classical: [sa.kroːˈsaːŋk.tʊs][1]
  • Ecclesiastical: [sa.kroˈs̬aŋk.tus][1]

Forms

sacrōsānctus (feminine sacrōsāncta, neuter sacrōsānctum); first/second-declension adjective[1]

Etymology

It is a compound of sacrō, probably the ablative of sacer (“sacred”) or of sacrum (“religious rite”), and sānctus (“consecrated”), the participle of sanciō (“to make sacred”).[2][3][1] Wiktionary traces both elements to Proto-Indo-European *seh₂k- (“to make a pact; to make sacred”).[1]

Earliest recorded meaning

Köbler dates it from Cicero,[4] who in the speech against Catiline asks someone whether he thinks his estates will be sacrosanct while all else is laid waste.[5]

Semantic evolution

Lewis & Short give its first sense as consecrated with religious ceremonies, and so declared inviolable.[5] It is above all the word for magistrates protected by a religious sanction: Livy reports that the plebs were granted magistrates of their own who were to be sacrosanct, and calls the tribunes' power sacrosanct, created to defend liberty.[2][5] Tacitus and Pliny the Elder use it in the same sense.[2] After Augustus it also means sacred or venerable in general: Pliny the Younger says that Corellia's memory is sacred to him, and Apuleius calls Rome the sacrosanct city.[2][5] It is sometimes written separately, and Pliny the Elder splits it, sacrōque sānctum.[5][2] In medieval Latin the neuter plural sacrōsāncta means relics or other holy objects touched when an oath is taken.[6] Stelten gives "sacred, most holy, inviolable" for Church Latin.[7]
