köken: Ultimately from Latin synthesis, from Ancient Greek σύνθεσις (súnthesis, “putting together; composition”). Compare French synthèse f, German Synthese f, Polish synteza f, which may have influenced the syllable stress but not the grammatical gender. Masculine gender is likely due to the East Slavic forms: Belarusian сі́нтэз m (síntez), Russian си́нтез m (síntɛz), Ukrainian си́нтез m (sýntez).
