What language is pseudocode written?

Pseudo code is in itself a language on its own.

Pseudo codes are used to describe algorithms in computer science. This language, unlike a programming language is used for human specific understanding and abstract representation of a certain procedural flow of a program. Pseudo code cannot be executed in a computer based environment.

Pseudo code eliminated unnecessary programming structures and only focuses on the flow process of the algorithm. It includes programming language specific constructs and natural human language constructs to explain the functioning.

This is unlike a computer programming language where strict rules and procedures are laid down, which have to be followed to execute the particular code.
