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.

Etymology
Origin of teach
First recorded before 900; Middle English techen, Old English tǣcan; akin to token
Explanation
To teach is to transfer ideas or skills to another person. As an old saying goes, "Give someone a fish, they eat for a day, teach someone to fish and they eat for a lifetime." I hope they like seafood. The Old English word tǣcan, which became the Middle English techen, meant "to show or point out." But the Old English also had another word for teach — læran — which eventually became the modern "learn," with the current meaning of receiving knowledge rather than giving it. If someone tries to "teach you a lesson," he or she tries to punish you for something you've done in order that you won't do it again.
