Which of the following best describes a proword?

• A. A term used to indicate the end of a transmission
• B. A word used to indicate encryption
• C. A word with a defined meaning for expeditious handling
• D. A phrase used to request permission

Answer: (C)

Prowords are standardized, single-word terms used in radio communications to convey a specific, predefined meaning quickly and unambiguously. They are designed to keep messages short and clear, so everyone understands the exact instruction or status without lengthy phrasing. That’s why the best description is a word with a defined meaning for expeditious handling—each proword has a precise purpose in the flow of communication.

Some prowords do relate to transmission flow, like indicating you’re finished speaking, but the broader idea is that prowords are concise, universally understood terms for fast handling. They are not encryption indicators or phrases requesting permission. For example, terms like “Roger” (message received) or “Wilco” (will comply) illustrate how a single word can convey a specific, actionable meaning in real-time dialogue.
