doceo

From Proto-Italic *dokeō, from earlier *dokejō, causative of Proto-Indo-European *deḱ- (“to take”). Cognate with Ancient Greek δοκέω (dokéō, “I expect, suppose, seem”) and Ancient Greek δέχομαι (dékhomai, “I accept, receive”). The sense "rehearse, present on stage" is a semantic loan from Ancient Greek διδάσκω (didáskō).
