periegesis

Borrowed from Koine Greek περιήγησις (periḗgēsis, “the action of being shown around, as by a guide (chiefly in the titles of works)”), from Ancient Greek περι- (peri-, “around, surrounding”) + ἥγησις (hḗgēsis, “command, leading”) (from ἡγέομαι (hēgéomai, “to lead”) + -σῐς (-sĭs, noun-forming suffix)), from περιηγεῖσθαι (periēgeîsthai, “to lead around”); compare Late Latin periegesis. Cognate with Greek περιήγηση (periígisi, “tour, sightseeing”).
