# Parse tree

Parse tree\. Another name: derivation tree \(DT\)\. The result of grammatical analysis\. The parse tree differs from the [abstract syntactical tree](https://pvs-studio.com/en/blog/terms/0004/) in that it contains nodes for those syntactic rules which do not influence the program semantics\. A classical example of such nodes is grouping parentheses, while grouping of operands in AST is explicitly defined by the tree structure\.
