Lexical analysis breaks the source code text into small pieces called tokens.
Semantic analysis is the phase in which the compiler adds semantic information to the parse tree and builds the symbol table.

Lexical analysis involves tokenizing the input text into basic units (tokens) such as words or symbols. Semantic analysis focuses on understanding the meaning of those tokens and their interrelationships within the context of the language or domain. In other words, lexical analysis deals with the structure and basic syntax, while semantic analysis delves into the deeper meaning and interpretation of the text.

What is lexical conditioning?
Lexical conditioning refers to the influence of individual words or lexical items on the pronunciation, meaning, or grammar of other words in a language. It occurs when the form or behavior of one word is affected by another word, often when they are adjacent to each other in a phrase or sentence.
What is the lexical approach?
The lexical approach is a method of language teaching that focuses on vocabulary and collocations as the building blocks of language. It emphasizes learning chunks of language as they occur naturally in context, rather than studying vocabulary in isolation. The goal is for learners to develop fluency and accuracy by becoming proficient in using lexical items and phrases in authentic communication.
Is an IQ score of 172 high for a twelve year old?
Ideally, the IQ score is independent of the subject's age. 172 is a totally unbelievable IQ score for anybody; before it is accepted as fact, the test should probably be repeated. +++ Even if the figure was a misprint for 127, that would still be a high IQ BUT it is important to remember IQ is not everything. Standard IQ tests tend to be limited to testing skills with various numerical, lexical and pattern puzzles; and are not a reliable guide to the subject's learning ability or future academic results.
What is the difference between a semantic field and a lexical field?
Semantic field is the meaning behind the words like 'oxygen' and 'catalyst' would have a semantic field of science and lexical field is just....the words i think....

What is the grammatical difference between scientia and scientifica?
There is no grammatical difference between two nouns. If they have different meaning, then there is a lexical difference.
What are the Classification of tokens in lexical analysis?
the classification of token
Compare with lexical analysis and syntax analysis?
Lexical analysis involves breaking down the input into tokens, identifying keywords and operators, and removing whitespace and comments. Syntax analysis checks the structure of the tokens to ensure they conform to the grammar rules of the language. In summary, lexical analysis focuses on individual elements, while syntax analysis focuses on how these elements combine to form meaningful expressions.
What is difference between Lex and Yacc?

What is the need for separating analysis phase into lexical analysis and parsing?
Separating the analysis phase into lexical analysis and parsing helps to break down the process of interpreting the structure of a source code into more manageable steps. Lexical analysis focuses on breaking the input into tokens, which are the smallest meaningful units, while parsing constructs a parse tree or syntax tree to represent the grammatical structure of the code. This separation allows for easier maintenance, testing, and implementation of new features in the compiler or interpreter.
What is lexical retrieval?
Lexical retrieval refers to the process of accessing and retrieving words from memory during language production. It involves selecting the appropriate words to express our thoughts and ideas. This process can be influenced by various factors such as word frequency, semantic relationships, and cognitive demands.
