Reconstruction:Proto-Indo-European/h₂ŕ̥tḱos(Redirected from Appendix:Proto-Indo-European/h₂ŕ̥tḱos)
The word is either a nominalization of an unattested adjective *h₂r̥tḱós (“destroying”) or a derivative of *h₂rétḱes (“destruction”) (cf. Avestan [script needed] (rašah), Sanskrit रक्षः (rákṣaḥ)).
In late PIE (i.e. post-Anatolian period) the word metathesized into *h₂ŕ̥ḱtos which phonetically surfaced as *h₂ŕ̥ḱþos following the rule that when dental and velar occlusives appear syllable-initially, they metathesize tk → kt and turn into a thorn cluster denoted ḱþ. See Wikipedia for a discussion of these clusters' makeup.
