Explain Terminal Symbols

Terminal symbols are literal strings that are forming the input of a formal grammar and cannot be broken down into smaller units with no losing their literal meaning. In straightforward words, terminal symbols cannot be changed by using the rules of the grammar; i.e. they're the end of the line, or terminal. For instance, if the grammar rules are that x can become xa and x can become ax, after that a is a terminal symbol as it cannot become something else. These are the symbols that can take place as it is in the programme.
