köken: Derived from Proto-Turkic *dï̄n + -(n)c. Azerbaijani tıncıxmaq (“to pant”) and dincəlmək are derivations of the same root. Cognate with Turkish dinç, Bashkir тыныс (tınıs), see there for more.
köken: Inherited from Old Polish spokojny, from Proto-Slavic *sъpokojьnъ. Cognate to Russian споко́йный (spokójnyj). By surface analysis, z- + pokój + -ny
köken: From Old Irish sám, from Proto-Celtic *sāmos. According to Matasović, this adjective is a vṛddhi formation on Proto-Indo-European *somos (“same”), ultimately from Proto-Indo-European *sem- (“one, same”) and parallel to German sanft, English soft; however, "the semantic side of the connection leaves much to be desired".
