Which word means to explain the exact meaning of a particular word or idea?

• A. Define
• B. Delineate
• C. Describe
• D. Design

Answer: (A)

The main idea here is expressing the exact meaning of a term. To define a word is to state its precise sense and the boundaries of what it covers, which is exactly what it means to explain the exact meaning of a word or idea. Delineate can involve outlining limits or features, but not necessarily pinning down the precise meaning in a dictionary-like way. Describe focuses on portraying appearances or details, not necessarily setting the exact sense or scope. Design is about planning or creating something, not about clarifying meaning. For example, define a term by giving its clear, specific meaning and what it includes or excludes.
