didactic

"Didactic" describes something intended to teach or instruct, especially when it also tries to deliver a moral lesson. It's more than just providing information; a didactic work actively aims to impart knowledge or a lesson, often with a strong emphasis on what is right and wrong.

Originally, "didactic" simply meant "relating to teaching" and could be used in a neutral way. Over time, it has developed a slightly negative connotation. While a good teacher can be didactic without being annoying, the term often suggests a heavy-handed or preachy approach.

You might describe a novel as "didactic" if its characters primarily exist to illustrate a point, and the plot serves mainly to deliver a moral message. A film that relentlessly hammers home a political agenda could also be considered didactic. Even a parent's constant lecturing can be described this way! ("His father was very didactic about the importance of hard work.")

It's important to note that being instructive isn't always didactic. A textbook can teach without feeling like a lecture. The key difference is often the tone—does it simply explain, or does it keep pushing a lesson and steering you toward a particular conclusion?

So, while "didactic" can describe effective teaching, be aware that it often carries a hint of disapproval—suggesting an overbearing or overly moralizing tone. It's about how something teaches, not just that it does.
