S-expression grammar for a tiny subset of English written as an s-expression (Gazdar/Melish, Natural Language Processing in Lisp): Program code can be written in S-expressions, usually using prefix notation. Example in Common Lisp: S-expressions can be read in Lisp using the function READ. READ reads the textual representation of an s-expression and returns Lisp data. The function PRINT can be used to output an s-expression. The output then can be read with the function READ, when all printed data objects have a readable representation. Lisp has readable representations for numbers, strings, symbols, lists and many other data types. Program code can
