True, most compilers

and interpreters

contain a component called a parser that extracts the meaning of a program before generating the compiled code or performing the interpreted execution.

A parser is a software component that processes text and checks its semantic

correctness. It's a program that's usually part of a compiler and receives input in the form of sequential source program instructions, interactive online commands, markup tags, or some other defined interface.

A parser builds an internal representation of the text structure, which is called a parse tree. The parser breaks data into smaller elements for easy translation into another language.

The term "parsing

$"$ comes from the Latin word pars, which means "part"
