xenagogue

Learned borrowing from Ancient Greek ξεναγωγός (xenagōgós), from ξένος (xénos, “foreigner; guest; stranger”, noun) (possibly ultimately Pre-Greek) + ἀγωγός (agōgós, “(adjective) guiding, leading; (noun) escort, guide”) (from ᾰ̓́γω (ắgō, “to bring along, lead”) (ultimately from Proto-Indo-European *h₂eǵ- (“to drive”)) + -ός (-ós, suffix forming agentive or patientive adjectives and nouns)). By surface analysis, xen- (prefix meaning ‘relating to foreigners or strangers’) + -agogue (suffix denoting something leading to another thing).
