- Ultimate origin

Forms
intāctus (feminine intācta, neuter intāctum); first/second-declension adjective[1]
Etymology
It is formed from in- (“not”) and ⟨tāctus⟩, the past participle of tangō (“to touch”).[2][1][3] De Vaan traces the participle to Proto-Italic *tagto- and Proto-Indo-European *th₂g-to-, from the root of Ancient Greek τεταγών (tetagṓn, “having seized”) and Gothic 𐍄𐌴𐌺𐌰𐌽 (tēkan, “to touch”); its long ⟨ā⟩ is due to Lachmann's law.[4] The older formation of the same meaning is integer, from Proto-Italic *ntagro- (“untouched”).[4]
Earliest recorded meaning
Köbler gives Lucretius as its first author,[5] and the OLD's examples begin with Cicero, who says that the citadel of Rome remained safe and untouched (incolumis atque intācta).[2]
Semantic evolution
It is untouched, and so undamaged, food uneaten, and wealth not plundered (Horace).[2] Of living beings it is unhurt, as Sallust's “no one escaped unscathed”, of peoples unconquered, as Horace's Briton, and of women virgin, as Virgil's Dido.[2][6] It is also untouched in reputation (Caelius' Hortensius had reached old age without a hiss), unaffected by something, and unused or untried, of land never tilled and oxen never yoked.[2]
Church Latin glosses it “inviolate, untouched, untried”.[7] English intact (mid-15th century) comes from it.[3]
