Etymology : Pedagogical, which has the somewhat less common variant form pedagogic, was coined in the early 17th century from a Greek adjective of the same meaning. That adjective, paidag?gikos, in turn, derives from the noun paidag?gos, meaning “teacher.” The English word pedagogue (which can simply mean “teacher” but usually suggests one who is particularly pedantic or dull) derives from the same root. Although the words educational and teacher make the grade in most contexts, pedagogical and pedagogue are useful additions to the class.
