Where the word didactic comes from

The Greek root

Merriam-Webster says the English word comes from New Latin didacticus, which was borrowed from the Greek didaktikós, meaning "apt at teaching." The Greek comes from didáskein, "to teach, instruct." Merriam-Webster dates the first known use in English to 1658.

The Online Etymology Dictionary gives the same Greek, from didaktos, "taught," and says the word reached English in the 1650s by way of French didactique. The two dictionaries differ on the route, so we name both. Wikipedia's article on didacticism glosses the Greek as "pertaining to instruction."

A good word first

Pablo Helguera, an artist and educator, writes that the word first meant apt at teaching and carried no negative charge. He turns to modernism, with its focus on a work standing on its own, as the point where it became a put-down.

Wikipedia says that around the 19th century it became a criticism of works overloaded with teaching at the cost of enjoyment, and notes that Edgar Allan Poe called didacticism one of the worst "heresies." Merriam-Webster still lists the first sense as simply "designed or intended to teach," and adds that the word is often used with disapproval.

Didactic in art and design

Wikipedia says that in art, design, architecture and landscape, didacticism is an approach driven by "the urgent need to explain." That is the sense we mean: a piece that is built to show you how it works.

The wall labels in museums come from the same idea. We say more about them on the page about our style.

In Jeffrey's view

For Jeffrey, the idea that matters most is a didactic that looks in at itself: the work shows how it was made. That is his view, in his words, and not something any of these sources say.
