Pronunciation

  • IPA (Classical): [ˈkʷɪs][1]
  • IPA (Ecclesiastical): [ˈkʷis][1]

Forms

quis or quī or quei (feminine quae or quis or qua, neuter quid); interrogative/indefinite pronoun (with m optionally → n in compounds)[1]

Etymology

It is inherited from Proto-Italic *kʷis, inherited from Proto-Indo-European *kʷís (“who, what; someone”), the interrogative and indefinite stem.[2][1] The neuter ⟨quid⟩ continues *kʷid; the forms of the feminine and of the genitive and dative singular were supplied by the relative stem (see quī).[2][3] The indefinite pronoun “anyone” is the unaccented form of the same word.[3]

Cognate with Oscan pis and Umbrian pisi, Ancient Greek τίς (tís), Sanskrit किम् (kím, “what”) and Hittite kuiš.[2][3]

Earliest recorded meaning

It is found in the Twelve Tables and in Livius Andronicus.[2][4]

Semantic evolution

As an interrogative it asks “who?” and in the neuter quid “what?” or “why?”; it is used substantivally, while quī is the matching adjective.[3][5] As an indefinite pronoun it means “anyone, anything”, especially after sī, nisi, num and nē (sī quis “if anyone”, nē quis “that no one”).[3][5]

The old nominative plural quēs survives in the senatorial decree on the Bacchanalia and in Pacuvius.[3][5]

Timeline

  • c. 450 BC – Used in the Twelve Tables.[2][4]
  • c. 250–184 BC – Plautus uses quis of women too.[3][4]

Meanings

Usage notes

Quis is properly used of more than two; for “which of two?” Latin uses uter.[5][1]
