Forms

abditus (feminine abdita, neuter abditum); first/second-declension adjective[1]

Etymology

Used as an adjective, it is the past participle from Latin abdō (“to put away, hide”).[1][2] De Vaan counts abdō among the compounds of -dō, which go back to Proto-Italic *-þō and the root Proto-Indo-European *dʰeh₁- (“to put”), whose simple verb Latin has not kept.[3] Cognate with Ancient Greek τίθημι (títhēmi, “to put”).[3]

Earliest recorded meaning

Köbler's first source is Cicero,[4] who speaks of animals hidden and covered with earth.[1]

Semantic evolution

It means hidden from sight or concealed, and of places out of the way or secluded, as Cicero's “what place was so remote that it was hidden?”[1] Lucretius uses the neuter plural as a noun, of the hidden parts of the earth that miners search out with iron.[1] Figuratively it is hidden from knowledge, abstruse, as Cicero's “hidden and obscure things”, and of expressions obscure in meaning.[1] Church Latin glosses it “concealed, hidden”.[5]

Timeline

  • 96–55 BC – Lucretius of the hidden parts of the earth.[1][4]
