Did You Know?
"Didaktikos" is a Greek word that means "apt at teaching." It comes from "didaskein," meaning "to teach." Something "didactic" does just that: teaches or instructs. "Didactic" conveyed that neutral meaning when it was first borrowed in the 17th century, and still does; a didactic piece of writing is one that is meant to be instructive as well as artistic. Parables are generally didactic because they aim to teach a moral lesson. "Didactic" now sometimes has negative connotations, too, however. Something "didactic" is often overburdened with instruction to the point of being dull. Or it might be pompously instructive or moralistic.
