Pronunciation

  • IPA (Classical): [ˈkʷiːn][1]
  • IPA (Ecclesiastical): [ˈkʷin][1]

Forms

quīn (not comparable)[1]

Etymology

It is formed from the old ablative quī “how, why” and the negative particle nē, first “why not?”.[2][3][1][4][5] De Vaan explains the adverb ⟨quī⟩ as an old instrumental Proto-Indo-European *kʷih₁ of the interrogative pronoun.[6] Wiktionary takes the conjunction rather from the relative ⟨quī⟩ and its ablative, “by which not”.[1]

Earliest recorded meaning

Köbler dates it from Plautus;[5] his characters use it in exhortations, quīn tū hīc manēs?, “why don't you stay here?”, and in subordinate clauses after verbs of hindering.[2]

Semantic evolution

As an adverb quīn asks “why not?” in questions that amount to commands, and introduces a statement that confirms and outdoes what precedes, “indeed, in fact”;[2][3][1] quīn etiam adds a stronger point, “and what is more”.[2][3][1]

As a conjunction, after negative or quasi-negative clauses, it means “who does not, but that, without”, “from (doing)” after verbs of hindering and delaying, and “that” after expressions of not doubting.[2][1] Church Latin keeps the same range.[4]

Timeline

  • c. 250–184 BC – Plautus: quīn tū hīc manēs?;[2][5] quid tū dubitās quīn … fūr lēnō siet?, “why do you doubt that the pimp is a thief?”[2][5]
  • 190–159 BC – Terence: nec mora ūllast quīn eam uxōrem dūcam, “there is nothing to stop me marrying her”.[2][5]
  • 234–149 BC – Cato tells the farmer not to let the fire go out, quīn semper siet, “so that it is always burning”.[2][5]
