What are the key differences between syntax and semantics?.

Syntax refers to the set of rules that govern the structure of sentences, including word order and sentence formation. Semantics, on the other hand, deals with the meaning of words, phrases, and sentences. Key differences include:

Key Facts

• Definition: Syntax is about structure; semantics is about meaning.
• Focus: Syntax focuses on how sentences are formed; semantics focuses on what sentences mean.
• Examples: "The dog bites the man" has a different syntax from "The man bites the dog," but semantics can overlap.
• Errors: Syntax errors often lead to ungrammatical sentences; semantic errors lead to sentences that are grammatically correct but nonsensical.

Examples or Use Cases

• Syntax is crucial in programming languages for code execution. Semantics is vital in linguistics for understanding context and meaning.

FAQs

• What is an example of a syntax error? A sentence like "The quickly dog runs" is syntactically incorrect.
