Teach, instruct, tutor, train, educate share the meaning of imparting information, understanding, or skill. Teach is the broadest and most general of these terms and can refer to almost any practice that causes others to develop skill or knowledge: to teach children to write; to teach marksmanship to soldiers; to teach tricks to a dog. Instruct almost always implies a systematic, structured method of teaching: to instruct paramedics in techniques of cardiopulmonary resuscitation. Tutor refers to the giving of usually private instruction or coaching in a particular subject or skill: to tutor a child in (a foreign language, algebra, history, or the like). Train lays stress on the development of desired behaviors through practice, discipline, or the use of rewards or punishments: to train a child to be polite; to train recruits in military skills; to train a dog to heel. Educate, with a root sense of “to lead forth from,” refers to the imparting of a specific body of knowledge, especially one that equips a person to practice a profession: to educate a person for a high-school diploma; to educate someone for the law.

Word Origin & History

O.E. tæcan (past tense and pp. tæhte) "to show, point out," also "to give instruction," from P.Gmc. *taikijanan (cf. O.H.G. zihan, Ger. zeihen "to accuse," Goth. ga-teihan "to announce"), from PIE *deik- "to show, point out" (see diction). Related to O.E. tacen,
tacn "sign, mark" (see token). O.E. tæcan had more usually a sense of "show, declare, warn, persuade" (cf. Ger. zeigen "to show," from the same root); while the O.E. word for "to teach, instruct, guide" was more commonly læran, source of modern learn and lore.
