Proto-Indo-European

Etymology

A PIE interrogative-indefinite paradigm built from the stems *kʷi- and *kʷe- (parallel to anaphoric *i-, *e-), the former on nominative and accusative cases of all genders, the latter elsewhere, with no distinction of feminine forms, mostly "human" – "non-human". A stem *kʷo-, an o-stem adjective, with its corresponding feminine *kʷeh₂-, was originally separate, but in most languages there was some conflation with the other two, as it is from this function that the relative pronoun evolves. Ultimately from *kʷ-.

Pronoun

*kʷís

1. who, what (interrogative)
2. who, which, that (relative)
