This category is for programming languages which were created, and have as a main or major purpose, to educate and teach about language concepts, design, programming, and/or larger, more general system issues; and/or support other types of education (networking, math, physics); languages existing solely or in large part, to educate. These usually start out far simpler than more general, or widely used languages, but some grow greatly, become very powerful, and find use in business or science; examples: BASIC, Pascal, Python, Smalltalk. Mostly the links in this category point to other language categories and languages there. The only languages listed exclusively here are those for which no better or clearer category seems suitable.
