Concept:Language is a structured, rule-governed system of symbols that humans use to communicate thoughts and feelings. It is composed of multiple smaller systems, such as sounds, words, and patterns, which work together as one whole.
Explanation:Language has no natural link between words and their meanings; it is arbitrary. It follows a set of rules (grammar) and is learned through culture. Because it includes subsystems like phonology, morphology, and syntax, it is best described as a ‘system of systems.’ This means that language is not just a single system but a complex network of interrelated parts. The other options—grammar system, scientific system, or social institution—are either too narrow or not as comprehensive. For example, grammar is only one part of language. Hence, language is fundamentally a system of systems.
Answer:A. a system of systems.
