Which are the core properties of human language?

• A. Productivity
• B. Recursivity
• C. Displacement
• D. All three

Answer: (D)

Three features define human language: productivity, recursivity, and displacement. Productivity means we can combine a finite set of sounds or signs into an endless variety of messages, including things we’ve never heard before. Recursivity is the ability to embed ideas inside other ideas, creating nested, hierarchical structures like clauses within clauses. Displacement lets us talk about things not present here and now—past events, future plans, hypothetical situations, and distant places. Together, these properties explain why language supports unlimited expression, complex idea-building, and reference beyond the immediate moment. All three are essential.
