Lexical analysis is the process of breaking down a language or text into its individual components, such as words, phrases, and symbols, in order to understand its structure and meaning. This method is commonly used in linguistics, computer science, and natural language processing to analyze and categorize the vocabulary and grammar of a given language. Through lexical analysis, one can gain a deeper understanding of the intricacies and nuances of a language, allowing for more accurate and efficient communication. It is a crucial tool for language study and development, as well as for creating advanced technologies that rely on language processing.
