^ Derksen, Rick (2008 ) “*rekti”, in Etymological Dictionary of the Slavic Inherited Lexicon (Leiden Indo-European Etymological Dictionary Series; 4), Leiden, Boston: Brill, →ISBN , page 433 : “v. (c) ‘speak, say’ ”
From earlier *regti , further etymology uncertain. Boryś derived descentands from *ręgati /*rǫgati ( “ to offend , to scorn ” ) and Brückner derived Slovene régniti from *ręžati ( “ to have a wide open mouth ” ) . All ultimately from Proto-Indo-European *wreng- ( “ to twist , wring ” ) . That makes missing nasal in Polish problematic.
Łuczyński proposed to derive it from Proto-Indo-European *h₁regʷ- ( “ to be dark ” ) . For meaning shift from “dark, black” > “empty” compare Sanskrit रजस् ( rajas , “ darkness; space ” ) , Tigrinya ፀሊም ( ṣ́älim , “ black, dark, empty ” ) . The original Slavic meaning could therefore be “to make blanks ”, which was narrowed down to “to cut”.
