doceo (Latin)

Where does "doceo" come from?

The Latin verb 'doceo', meaning to teach or instruct, developed from the Proto-Italic form '*dokeō'[1][3]. This Italic term traces back to the Proto-Indo-European root '*deḱ-', meaning 'to take'[1][3]. Over time, the Latin verb acquired the sense of rehearsing or presenting on stage through a semantic loan from the Ancient Greek verb 'διδάσκω'[1]. Related terms reflecting this deep ancestry include the Ancient Greek forms 'δοκέω' and 'δέχομαι'.

Open questions
