When deciding whether to use an acronym, which principle should guide your choice?

• A. Economy
• B. Brevity
• C. Avoid acronyms entirely
• D. Clarity before economy

Answer: (D)

Clarity should guide whether you use an acronym. Acronyms save words only if the audience will understand them, so you should use them when they actually aid comprehension or when you can define them upfront. If the readers are familiar with the term, the acronym can speed up communication; if not, spell it out and introduce the abbreviation on first use, then you can switch to the acronym afterwards. This is why prioritizing clarity before economy is the best choice—it keeps the message clear while still allowing efficient communication when appropriate.
