Lexical Analysis

Lexical analysis is the process of breaking down text into smaller units called tokens to understand its structure and meaning. In programming and language processing, this involves identifying words, numbers, and symbols within the text. Think of it as turning a sentence into its building blocks, which can then be analyzed further for syntax and grammar. This step is crucial in various applications, such as compiling computer code or processing natural language, as it helps systems recognize and interpret the components of the text effectively.
