LSP Dictionary is a type of dictionary that helps you to understand the words and phrases used in a programming language called Lisp (or LSP, for short). The dictionary explains all the terms and concepts used in the language, so you can understand what the code is doing and why. It has definitions for all the keywords, operators, and functions used in Lisp, and it also includes examples of code that show how the language works. With an LSP Dictionary, you can easily understand any Lisp code you come across.
