Which word means occurring yearly?

• A. Transfer (a Phone Call)
• B. Annual
• C. Phone Extension
• D. AIDS (Acquired Immune Deficiency Syndrome)

Answer: (B)

Understanding how often something happens is about frequency words. The word that means occurring yearly is annual, which refers to events or actions that happen once each year—for example, an annual meeting or an annual report. The other options don’t express frequency: transferring a phone call is about moving the call to another line, a phone extension is a reachable number, and AIDS is a medical condition. So annual is the word that clearly conveys “once per year.”
