Which of the following is NOT a characteristic of natural language?

Natural language is characterized by several features that make it rich and dynamic. Contextual richness refers to the ability of language to convey meaning based on the situation and environment in which it is used, displaying its flexibility and depth. Variability and ambiguity highlight that words and phrases can have multiple meanings depending on the context, which is a natural aspect of human communication. Furthermore, complexity in usage showcases the intricate ways in which language can be employed to express nuanced thoughts and emotions.

Strict grammatical rules, on the other hand, do not accurately reflect the inherent nature of natural language. While certain grammatical structures exist, natural languages often exhibit variations and deviations from these rules in everyday speech. People regularly use colloquialisms, regional dialects, and informal structures that do not adhere strictly to prescribed grammar, demonstrating that natural language thrives on fluidity rather than rigid adherence to rules. Therefore, the diversity and adaptability of natural language make strict grammatical rules an inaccurate representation of its characteristics.
