Which term refers to special words used by a profession or group that are difficult for others to understand?

• A. Anecdote
• B. Less common lexis
• C. Jargon
• D. List of three

Answer: (C)

Specialized language used by a profession or group that others struggle to understand is called jargon. It includes technical terms, abbreviations, and shorthand that insiders use to communicate efficiently. This question points to that exact idea—a word in everyday use wouldn’t capture the sense of a whole set of terms tied to a field, so jargon is the best fit. For example, in medicine you might hear terms like hypertension or ECG, which aren’t part of everyday vocabulary. Anecdote refers to a short personal story, not a type of language. Less common lexis simply means uncommon vocabulary in general, not necessarily tied to a specific profession. A list of three is unrelated to language at all.
