What is the role of lexico-grammar in language, and how does it differ from simpler semiotic systems? Lexico-grammar serves as an intermediate level in the language system that codes meanings between content and expression (sounds). Unlike simpler semiotic systems (e.g., traffic lights) that have a one-to-one correspondence between meaning and expression with limited meanings, the lexico-grammar allows language to break this bi- unique relationship. This enables an infinite number of meanings to be g enerated from a finite set of sounds, by combining units (words) into grammatical structures. 2. Explain the concept of simultaneous meanings in language. Provide an example of a sentence that illustrates this concept. Simultaneous meanings mean that a single linguistic unit conveys multiple layers of meaning at once.
