Forms

sānctitās f (genitive sānctitātis); third declension[1]

Etymology

It is from Latin sānctus (“sacred, holy”) + -tās.[2][3][1][4] The adjective is the participle of sanciō (“to make sacred, ratify”), which Wiktionary traces to Proto-Indo-European *seh₂k- through a nasal present.[1]

Earliest recorded meaning

Köbler dates it from Cicero,[5] who in the Pro Sestio speaks of a man relying on the sacrosanctity of the tribunate.[2]

Semantic evolution

Its first sense is the state of being protected by religious sanction, inviolability, as of the tribunate, of kings in Caesar's words reported by Suetonius, or of a temple and island in Livy.[2][3] It also means the observance of religious duties, as Cicero's “all the sanctities and religious obligations of gods and men”.[2] Most often it is moral purity, virtue or integrity, as the purity Cicero says the name of a matron demands, and Quintilian applies it to purity of style.[2]

In medieval Latin sanctitas tua was a title of honour for bishops.[6] English borrowed sanctity through Old French in the late 14th century.[4]
