If the word educate makes you think of children, you're not far off. It comes from the Latin word educare meaning to "bring up, rear.” In the 1500s, Shakespeare borrowed it to mean "schooling." These days, any time you're in a classroom listening to a lecture, reading a book, or speaking with a teacher, you're being educated. Teachers educate students all the way from preschool to graduate school. Almost any experience can educate if you learn from it.
