I am reading this text and it is making absolutely no sense to me. It as if it assumed I will understand. Not to mention the writer apparently had a book made and his grammar is poor. Some of the plain English sentences do not even make sense or have the letter s on the end of words where they should not be. please help me understand this:Language generators. A language generator is a device that can be used to generate the sentences of a language. A generator seems to be a device of limited usefulness as a language descriptor. Generators can more easily read and understand them. A language generation method constructs a language generator G and capable of generating a string of language by a process called derivation. For example, consider a language L over alphabet = {a, b}L= {a^n, b^n|n  1}G = {  s -> asb   s -> ab   s -> 3(i need to turn this symbol the  opposite direction)}W = aaa bbbDerivation:S  asb   aasbb   aaabbbi.e., S  aaabbb It means we have derived aaabbb starting from start symbol S using the rules of language generator G in finite number of steps.
