Forms
occultō (present infinitive occultāre, perfect active occultāvī, supine occultātum); first conjugation[1] Plautus has the old perfect subjunctive occultāssis.[2][3]
Etymology
It is the frequentative of occulō (“to cover over, hide”), formed with ⟨-tō⟩ on the participle ⟨occultus⟩.[2][1][3] De Vaan explains ⟨occulō⟩ as ob with a verb ⟨*kele-⟩, from Proto-Italic *kele/o- and Proto-Indo-European *ḱel-e/o- (“to hide”), cognate with Old Irish ceilid (“hides”) and Old English helan (“to hide”); cēlō (“to conceal”) belongs to the same root.[4]
Earliest recorded meaning
Plautus, Curculio: tacē, occultēmus lūmen et vōcem, “quiet, let's hide the light and our voices”.[2]
Semantic evolution
It is to keep something out of sight, to hide (Plautus: I'll run away and hide myself for a few days), and to cover a sound, as the Curetes drowned the cries of the infant Jupiter in Crete (Lucretius).[2] Its most common figurative sense is to keep facts secret or suppress them, as Plautus' captive conceals his rank, family and wealth.[2]
Döderlein contrasts cēlō, to keep something from someone's knowledge, with occulere and occultāre, to hide something from view.[5] Church Latin glosses it “hide, conceal”.[6]
