Parse tree is nothing but the pictorial representation of the derivation process.

Link for video on Derivation is as below :

   • Derivation of a String | Leftmost & Rightm...  

Here, Root is always a Start symbol, Leaf modes are Terminals & Non leaf nodes are Non-Terminals.

If we concatenate all leaf nodes from left to right it gives a string called “Yield of a Tree”.

For a single string if there are two or more that two different parse trees available then that grammar is called as Ambiguous grammar.

Link for video on Ambiguous grammar is as below:
