What does didactical mean?
"Didactical" is an adjective describing something designed to teach or instruct — a lesson, text, or method that aims explicitly to impart knowledge or moral guidance. In neutral use, calling a work didactical simply notes its educational purpose, as with a textbook or a museum exhibit that explains its subject step by step. More often, however, the word carries a critical edge: a didactical novel or speech may feel preachy or condescending, more interested in delivering a lesson than in engaging its audience. The term is a less common variant of "didactic," which dominates modern usage; writers today rarely choose "didactical." Both words trace back through Latin didacticus to Greek didaktikos, from didaskein, "to teach." Related forms include the noun "didactics," the study of teaching, and "autodidact," a person who teaches themselves.
