A pedagogue began as a child-guide; in English it often becomes the teacher who guides too stiffly and talks too much.
The lecturer knew every rule but sounded like a pompous pedagogue rather than a helpful teacher.
The old paidagogos led the child to school. English kept the teacher idea, then added a warning label: a pedagogue can be a teacher whose learning has hardened into performance.
