Ultimate origin
Ancient Greek (ἄδυτος)

Pronunciation

  • Classical: [ˈa.dy.tũː][1]
  • Ecclesiastical: [ˈaː.di.tum][1]

Forms

adytum n (genitive adytī); second declension[1] Accius has a fourth-declension masculine adytus.[2][3]

Etymology

It is borrowed from Ancient Greek ἄδυτον (áduton, “innermost sanctuary”),[2][3][1] the neuter used as a noun of ἄδυτος (ádutos, “not to be entered”).[1][3] Köbler analyses the Greek word as ἀ- (a-, “not”) and δύω (dúō, “to enter”).[4]

Earliest recorded meaning

The OLD's first citation is Accius, who has a masculine accusative plural adytūs.[2][3]

Semantic evolution

It is the innermost part of a temple, the sanctuary, which only priests could enter and where oracles were given.[2][3] Caesar mentions the hidden and secluded parts of a temple that the Greeks call adyta.[3] Virgil has the eternal fire brought out of the inner shrine and sad words brought back from it, and Horace uses it too.[3] In general it is a secret place or chamber: Virgil and Juvenal use it of a tomb, and the Vulgate of inner rooms.[3] Lucretius speaks figuratively of answers given as if from the shrine of the heart.[3] Wiktionary gives sānctum sānctōrum as a synonym, and Stelten "sanctuary, holy of holies, inmost part".[1][5]
