What defines natural language?

• A. Natural language is language that was designed by humans for specific purposes.
• B. Natural language developed over time and was not designed from scratch.
• C. Natural language only refers to written text.
• D. Natural language is a formal system with fixed rules.

Answer: (B)

Natural language is language that develops organically through everyday use within a community, is passed down across generations, and isn’t designed from scratch. That evolving, generational nature means it grows with culture, varies by region and group, and shifts over time as people adopt new words, pronunciations, and rules.

This is why the statement describing natural language as something that develops over time and isn’t predesigned fits best. It contrasts with constructions that are created intentionally for particular purposes, which would be artificial languages. It also isn’t limited to written text—speech is a fundamental aspect of natural language—and it isn’t a rigid, fixed formal system, since natural languages are fluid, with exceptions, irregularities, and continual change.
