Pronunciation

  • Classical: [ˈat.kʷiː][1]
  • Ecclesiastical: [ˈat.kʷi][1]

Forms

atquī [1] It is also spelled atquīn, which Lewis & Short call post-classical; manuscripts sometimes have adquī.[2][3][4]

Etymology

It is from Latin at (“but”) + quī (“how, somehow”), here an adverb.[2][4][1][5] The TLL notes that in Plautus the particles have not yet fully grown together (⟨at pol quī⟩).[4] De Vaan traces at to Proto-Italic *ati and Proto-Indo-European *h₂et(i) (“back, away”), cognate with Ancient Greek ἀτάρ (atár, “but”).[6]

Earliest recorded meaning

De Vaan and Köbler date it from Plautus,[6][5] who uses it to open a reply: numquam auferēs hinc aurum. — atquī iam dabis, “you'll never get the gold from here. — But you'll give it in a moment”.[2]

Semantic evolution

Atquī introduces an objection to what has just been said, “but, and yet, nevertheless”, especially at the start of a reply in dialogue.[2][3] It also introduces a statement that goes the other way without contradicting, “but all the same”, and in philosophical argument it marks the minor premiss of a syllogism, “now, but” (Cicero).[2]

Church Latin glosses it “however, but, nevertheless”.[7]

Timeline

  • c. 250–184 BC – Plautus: atquī iam dabis.[2][5]
