Introduction

For comparative linguistics, the year 1969 brought a sensation: Professor Linus Brunner's book "The common roots of the Semitic and Indo-European Vocabulary", in which the author presents 1030 common Proto-Semitic and Proto-Indo-European roots and thus proves that both Proto-Semitic and Proto-Indo-European have a common ancestor language and are genetically related (Brunner 1969). In 1982, Brunner showed that Proto-Semitic and Proto-Indo-European share no less than 958 common roots with Proto-Malayo- Polynesian (Brunner 1982) as reconstructed by Dempwolff (1934-38). And in 1987, Brunner proved that Raetic - the ancestor language of Retoromanche - was a Semitic language, most closely related to Akkadian (Brunner and Tóth 1987). The Raetians - the only autochthonous Semitic people in Central Europe - thus came from the Euphrates-Tigris area as the Sumerians - the ancestors of the Hungarians - did. Although it is known since many years that Hungarian and Raetic have several words in common that cannot be attributed to borrowing (cf. Zimmern 1917, Lieberman 1977) nor change (cf. Beregszászi 1796, Kiss 1839) - for example Hung. gede, gide, Gödö-ll-A "goat" - Raetic gadu, kathu (Brunner and Tóth 1987, pp. 58, 98; Tóth 2007b, no. 55), Latin haedus, English goat, German Geiss, Swiss German Gitzi, etc., words like this could be Wanderwörter (migrating words) that do not prove much about the common origin of the Hungarians and the Raetians in Mesopotamia. Since it was proved in EDH, part 4 (Tóth 2007) that Sumerian- Hungarian shares 607 roots with Indo-European (as well as Semitic, qua Brunner 1969) and "Finno-Ugric", the little study about Hungarian réjteni "to hide", réjleni "to be hidden" and their derivations, that I will present here, may show in an exemplary way how it is possible to reconstruct truly Hungarian words, i.e. words that go back to the Sumerian ancestor language of Hungarian, under consideration that Sumerian survived also in many other languages between Northern Europe and the South Seas (cf. EDH-1-4, Tóth 2007).
