Can we create a new programming language?

Question

when we become a good programmer I think we can create a new programming language. As we can get an examples from today s programming languages.

Answer 1

hi you can actually do that. if we learn the principle of compiler we can understand how the code compiler we use do the process of scanning our code, parsing, semantic analyzing, till generating a target code from our intial code, which in normal case is the assembly language or machine language that enables computer to understand our "programming language" and do what it does... (essentially like the grammar of codes)

so we can actually create our own simple new programming language based on existing ones easily, but to have all kind of "functionalities" and libraries like existing ones will be much harder to do unless we r very knowledgable and skilled in computer science dept :)
