גאולוג

Originally from Ancient Greek γεω- (geō-), from γῆ (gê, “earth”) + Ancient Greek λόγος (lógos, “speech, oration, study”), likely via various Slavic languages—e.g. geolog, гео́лог (geólog), гео́лог (heóloh)—from which it was borrowed by Jewish bilingual speakers as Yiddish ⁧געאָלאָג⁩ (geolog), whence it made its way into the modern Hebrew lexicon.
