Which word means secret or hidden, often for illicit purposes?

• A. Aberration
• B. Clandestine
• C. Anachronism
• D. Approbation

Answer: (B)

The main concept here is recognizing a word that conveys secrecy and concealment, especially when tied to illicit or unauthorized activity. Clandestine describes actions, meetings, or operations kept secretly hidden to avoid detection, often because they’re illegal or suspicious. That direct sense of hidden intent makes it the best fit for “secret or hidden, often for illicit purposes.”

For context, aberration means a deviation from the norm, not secrecy; anachronism refers to something out of its proper time period; and approbation means praise or approval. So they don’t capture the idea of secrecy in the way clandestine does. For example, a clandestine meeting implies planning something covert, underscoring the secretive nature of the activity.
