A parse tree is a graphical representation of a [[#Derivation|derivation]]. Each interior node of a parse tree represents the application of a [[#Production|production]] and it is labeled with the name of the [[#Nonterminal|nonterminal]] that is the [[#Production_Head|head]] of the production. The children node are labeled, from left to right, by the symbols in the body of the production. A parse tree does not contain the information that reflects the order in which productions are applied to replace [[#Nonterminal|nonterminals]].

Parse Tree

A parse tree is a graphical representation of a derivation. Each interior node of a parse tree represents the application of a production and it is labeled with the name of the nonterminal that is the head of the production. The children node are labeled, from left to right, by the symbols in the body of the production. A parse tree does not contain the information that reflects the order in which productions are applied to replace nonterminals.
