Quiz #22 highlights a common misuse of the word, “moot.” It means a point that is “disputable or open to discussion.” (hence the phrase, “moot court”.) The word doesn’t imply that something is superfluous or beside the point, as was our guardrail on the missing bridge.
Dr. John’s Grammar Quiz #23: Can you spot the glaring grammatical error in this sentence? “The continuous blasts from the foghorn made it nearly impossible for us to sleep on the beach as we had planned.”
