The Howdy Glossary

Emacs Lisp is a dialect of the Lisp programming language that supports both compiled and interpreted code execution. It's used to extend the capabilities of GNU Emacs, an extensible text editor. Emacs Lisp can be used to modify parts of the interface or even add completely new functions to Emacs, making it a powerful tool for customization and automation. The language provides constructs for conditionals, loops, lexical scoping, and dynamic typing like other Lisps do.
