Concept:Language is a structured, rule-governed system that humans use to communicate. It is not just a collection of words; it consists of multiple interlinked subsystems like sounds, words, and grammar.
Explanation:Language has several key features: it is symbolic, arbitrary, and learned through culture. It is also creative and allows us to talk about things not present. These features show that language is not a single, simple system. Instead, it is made of several smaller systems: the sound system (phonology), the word system (morphology), the sentence system (syntax), and the meaning system (semantics). Each subsystem works within a larger framework. For example, sounds combine to form words, words combine to form sentences, and sentences carry meaning. This layered structure is why linguists call language a "system of systems." Options A, B, and D describe only one aspect or are incomplete. Only option C captures the complete nature of language as a complex, multi-level system.
Answer:C. Language is a system of systems.
