Which word means to refer to casually or indirectly?

• A. Assertion
• B. Futile
• C. Innocuous
• D. Allude

Answer: (D)

The main idea here is identifying a word that means referring to something indirectly or casually. Allude captures that sense: to allude to something is to hint at it or mention it without stating it outright. It’s like dropping a subtle reference rather than giving a direct, explicit statement. For example, you might say, “He alluded to the upcoming changes in his speech,” which shows the reference is indirect and not plainly stated.

The other words don’t fit the meaning as closely. An assertion is a strong or direct statement of fact. Futile describes something pointless or unable to succeed. Innocuous means something harmless or not likely to offend. None of these convey the idea of hinting or referring indirectly, which is why allude is the best choice.
