Etymology

It is the perfect participle of sanciō “to make sacred, ratify”, from Proto-Italic *sanktos, participle of *sankjō “to consecrate”.[2][1] An inscription has the participle ⟨sancītō⟩.[2] Köbler compares a PIE root *sak- “to sanctify”, and Döderlein connected it with Ancient Greek ἁγνός (hagnós, “pure”).[3][4]

Earliest recorded meaning

The OLD's earliest citation is from Livius Andronicus, of a holy god, and Ennius uses it of sacrosanct laws and holy things.[2] Köbler dates Livius Andronicus 280/260–before 200 BC.[3]

Semantic evolution

It meant secured by religious sanction, inviolable, of laws, persons in office such as tribunes, places and oaths, and Ulpian gives a legal definition of it.[2][5] It meant holy, sacred, of things under divine protection, and of gods holy, blessed, as in Livius Andronicus, of poets and prophets, the dead, parents, and the senate.[2] From Cicero it meant morally upright, blameless, virtuous, and in Quintilian of style pure, chaste.[2] Döderlein explains that sacer is what belongs to the gods, sānctus what is under their protection.[4]

In Ecclesiastical Latin it meant holy, saintly, godly, and as a noun a canonized saint, Sānctus is also the hymn of the Mass.[6] It passed through Old French saint into English saint in the early 12th century, and Sanctus itself, the angelic hymn, is recorded in English in the late 14th century.[7] It survives in Italian santo and Romanian sfânt.[1]
