Which term means specialized vocabulary used by people in the same professional or similar group?

• A. Jargon
• B. Logic
• C. Metaphor
• D. Message

Answer: (A)

Specialized vocabulary used by people in the same professional or similar group is jargon. Jargon refers to the terms, abbreviations, and shorthand that members of a field use to communicate quickly and precisely with each other. It helps experts convey complex ideas efficiently, though it can be opaque to outsiders. For example, in medicine you might hear terms like BP or ICU, and in software development you might encounter API or latency—these are typical jargon within those fields. The other options describe different concepts: logic is about the principles of reasoning, metaphor is a figure of speech used to compare things, and a message is simply the information being conveyed. Jargon best fits the description because it specifically denotes the specialized language of a professional group.
