Today's challenge presents one or more examples of English containing a possible mistake.
Look carefully. Read the sentence, conversation or short passage. Does anything sound unusual, incorrect or inappropriate?
Find the problem. Identify the mistake and think about why it's a problem. It might involve grammar, vocabulary, word order, a missing word or an expression that doesn't fit the situation.
Make it right. Correct the language while preserving the intended meaning. If more than one correction is possible, try finding alternatives.
Now read your corrected version aloud. Does it sound natural? Would you use it in a real conversation?
Extra challenge: Explain the mistake as though you were helping another English learner. Can you make your explanation simple, accurate & useful?
When you're ready, reveal the suggested answers to compare your corrections and explanations.
Remember: not every unusual expression is necessarily wrong. Sometimes the context, register or variety of English makes all the difference.
